Four men accused of killing&nbsp;<a href="https://www.wionews.com/world/man-who-rammed-car-into-crowd-in-barcelona-killed-another-before-fleeing-in-his-car-police-19273">13 people in Barcelona last week appeared </a>in court on Tuesday, a day after the <a href="https://www.wionews.com/world/barcelona-van-driver-killed-in-police-encounter-report-19279">alleged driver was shot dead by police</a>.

The four, the only ones still alive among the 12 men thought to constitute the group, were brought from Barcelona to Madrid and arrived at the High Court, which deals with terrorism cases, in a convoy of police vehicles with sirens wailing.

Police on Monday shot dead 22-year-old Younes Abouyaaqoub, who they had identified as the driver of the van that careered along the packed Las Ramblas boulevard in Barcelona on Thursday, leaving a trail of 13 dead and 120 injured from 34 countries.

After the attack, Abouyaaqoub escaped on foot, stabbing to death a man who was parking his car and fleeing in the vehicle.

Spanish newspaper La Vanguardia said on Tuesday he walked some 40 km (25 miles) from Sant Just Desvern, a town on the outskirts of Barcelona where he ditched the hijacked car, to Subirats, where he was shot dead.

Abouyaaqoub, who had changed clothes, walked by night and hid during the day, the paper said citing sources involved in the investigation.

Carlos Mundo, the top justice official in the Catalan government, said police were investigating whether Abouyaaqoub had any support while on the run.

&quot;It is clear that he must have had some form of logistics,&quot; he told Catalonia Radio.

Islamic State claimed responsibility for the van attack and a separate deadly assault, hours later, in the coastal resort of Cambrils, south of Barcelona.

In Cambrils, a car rammed into passers-by and its occupants got out and tried to stab people. The five assailants, who were wearing what turned out to be fake explosive belts, were shot dead by police, while a Spanish woman died in the attack.

In little more than a year, Islamist militants have used vehicles as weapons to kill nearly 130 people in France, Germany, Britain, Sweden and Spain.

Most of the 12 suspects lived in the town of Ripoll, set in forested hills beneath the Pyrenees north of Barcelona near the French border, and most were young men of Moroccan descent.

One of those who appeared before investigating magistrate Fernando Andreu was Driss Oukabir, whose passport was found in the abandoned van after the Barcelona attack.

He turned himself in to police, protesting his innocence and saying his younger brother Moussa Oukabir, 17, who was killed in Cambrils, had stolen his documents.

Also in court was Mohammed Aalla, owner of the Audi car used in the Cambrils attack. One of his brothers, Said, was killed in Cambrils and a second, Youssef, is believed by police to have died in an explosion at a house used by the plotters at Alcanar, southwest of Barcelona, the day before the Barcelona attack.

Mohamed Houli Chemlal, arrested after being hurt in the blast at Alcanar, also appeared in court as did Salah el Karib, who ran an internet cafe in Ripoll that, according to La Vanguardia newspaper, was used to send money to Morocco.

At Tuesday&#39;s closed-door hearing, Andreu planned to read out charges against the men expected to include counts of terrorism, murder and weapons possession. Andreu was then to ask the accused if they wish to testify, in which case he would question them.

The hearing was likely to end in the suspects being remanded in custody while the judge conducts an investigation that could take months or even years before a trial is organised.

A Ripoll imam who police suspect may have radicalised the young men, Abdelbaki Es Satty, is believed to have died in the explosion in Alcanar. Police believe the blast foiled the group&#39;s plans for a much bigger attack using explosives.

Catalan police said on Monday that, while all 12 of the suspects they were looking for were accounted for, an investigation into whether the cell had international links would go on.

French Interior Minister Gerard Collomb on Tuesday confirmed press reports that the Audi used in the Cambrils attack had been caught on camera speeding in the Paris area about a week earlier. Authorities did not know why it was there, he said.

French authorities were unaware of the existence of the Catalan cell, Collomb told BFM TV, saying they were &quot;exclusively Spanish&quot;.

Spanish police have sought information from Belgian authorities on a visit the imam, Es Satty, made there last year.

The four, the only ones still alive among the 12 men thought to constitute the group, were brought from Barcelona to Madrid and arrived at the High Court, which deals with terrorism cases, in a convoy of police vehicles with sirens wailing

Four men accused of killing 13 people in Barcelona last week appeared in court on Tuesday, a day after the alleged driver was shot dead by police. The four, the only ones still alive among the 12 men thought to constitute the group, were brought from Barcelona to Madrid and arrived at the High Court, which deals with terrorism cases, in a convoy of police vehicles with sirens wailing.

Four suspected Barcelona attack plotters appear in court

Spanish police said they had uncovered a cache of 120 gas canisters at a house believed to be the bomb-making factory of suspects in terror attacks that claimed 14 lives, as Barcelona mourned victims of the rampage.

The suspected jihadists had been preparing bombs for &quot;one or more attacks in Barcelona&quot;, regional police chief Josep Lluis Trapero told reporters, revealing that traces of TATP explosive had also been found.

But the suspects accidentally caused an explosion at the house on the eve of Thursday&#39;s attack in Barcelona -- an error that likely forced them to modify their plans. 
Instead, they used a vehicle to smash into crowds on Barcelona&#39;s Las Ramblas boulevard as it was thronged with tourists, killing 13 people and injuring about 100.

Several hours later, a similar attack in the seaside town of Cambrils left one woman dead. Police shot and killed the five attackers in Cambrils, some of whom were wearing fake explosive belts and carrying knives.

The Islamic State (IS) group claimed responsibility for the attacks, believed to be its first in Spain.

Police are hunting a Moroccan man suspected of driving the van used in Barcelona, and warn that he could be at large outside Spain.

&quot;We don&#39;t know where he is,&quot; said Trapero of the 22- year-old suspect, Younes Abouyaaqoub. 
In the small town of Alcanar, investigators were combing the rubble of a house believed to be the suspects&#39; bomb factory, and where the gas canisters were uncovered.

A French retiree Martine Groby, who lived next door, told AFP of her regret in notifying police about her neighbours.

She comes only several times a year to her pink-painted villa but noticed that four men &quot;who all speak French&quot; had been in the house next door since April.

&quot;They were very discreet, too discreet. The shutters were closed, there was no music, no children, no women,&quot; she recalled.

&quot;Sometimes they would stay just two days and they would leave. They said hello to me but never looked me in the eye,&quot; added the 61-year-old pensioner.

She said that on Wednesday she was flung to the floor by a violent blast.

&quot;I didn&#39;t know they were terrorists. I thought it was our gas canister that exploded,&quot; she said.

Traces of triacetone triperoxide (TATP) -- a homemade explosive that is an IS hallmark -- were also found at the house.

Investigators said they believe the terror cell comprised at least 12 men, some of them teenagers.

An imam, Abdelbaki Es Satty, is among the suspects, police confirmed.

He is believed to have radicalised youths in Ripoll, a small town at the foot of the Pyrenees, where several suspects -- including Abouyaaqoub -- grew up or lived.

Yesterday, police raided the imam&#39;s apartment there. Investigators are also looking for DNA traces to see if the imam may have been blown up in the explosion in Alcanar.

The imam was reportedly known to police, with Spanish media saying he had spent time in prison.

El Pais and El Mundo quoting anti-terror forces said the imam had met prisoners linked to the Al-Qaeda-inspired bombing of Madrid trains that killed 191 people in March 2004 in what remains the worst terror attack in Europe.

Nordeen El Haji, 45, who four months ago moved into the apartment that Satty occupied, said that &quot;on Tuesday morning, (the imam) left saying that he was going on vacation to Morocco.&quot;

&quot;He spoke little, spent most of the time with his computer in his room, and had an old mobile phone with no internet, and few books,&quot; said Satty&#39;s flatmate.

In the Moroccan town of M&#39;rirt, relatives of Abouyaaqoub accused the imam of radicalising the young man, as well as his brother Houssein.

&quot;Over the last two years, Younes and Houssein began to radicalise under the influence of this imam,&quot; their grandfather told AFP.

Most of the suspects are children of Moroccan immigrants, including Ripoll-born Moussa Oukabir, 17, one of five suspects shot dead in Cambrils. His older brother

Driss is among the four arrested.

A cousin said Moussa &quot;loved playing football, having a good time, chatting up girls&quot;. (AFP)

The suspected jihadists had been preparing bombs for 'one or more attacks in Barcelona', regional police chief Josep Lluis Trapero said
