Four Palestinians killed by Israeli fire in border clashes

Four Palestinian were killed in fresh clashes with Israeli forces inGaza on Friday, news agency AFP reported citing Gaza health ministry sources.

According to a report, four Palestinian who have been shot includes one 14-year-old and one 18-year-old. Both were shot in a separate incident by live ammunition.

Palestinians have been protesting at least weekly along the Gaza border since March.

The Israeli army said some 20,000 "rioters" had gathered at multiple sites along the border in this week's protest.

It also said that the protestors hurled "grenades and explosive devices in several different locations" and troops were firing "in accordance with standard operating procedures" but did not go into specific cases.

At least 191 Palestinians have been killed by Israeli fire in that time, the majority during border protests.

Smaller numbers have been hit by airstrikes or tank fire.

More than 700,000 Palestinians fled or were expelled from their lands during the war surrounding Israel's creation in 1948.

Israelis say allowing the so-called "right of return" would mean their country would cease to exist.
