Soleimani and al-Muhandis's deaths are a potential turning point in the geopolitics of the Middle East and Iran has vowed a "harsh" response.
When my father's blood would be avenged?
President Hassan Rouhani, visiting Soleimani's family members at their house in Tehran said "The Americans really did not realise what grave error they have committed.
One of Soleimani's daughters asked the president "when the blood of her father would be avenged".
"Revenge for his blood will be exacted on that day when the filthy hands of America will be cut off forever from the region."
'Death to America!'
Thousands of Iraqis chanting "Death to America" joined the funeral procession for Iranian military commander Qasem Soleimani and Muhandis, both killed in a US air strike.

Tensions since the US airstrike on Baghdad has been escalated in between USA and Iran, Iraq and entire Middle East region.
'We will take our revenge!'
Soleimani's body was flown to the city of Ahvaz in southwest Iran.
