GAZA CITY (Ma'an) -- A man died on Tuesday from injuries sustained in an Israeli attack on Gaza days earlier, a medical official said.

Muhammad Zeyad Abdullah Quno, 20, was wounded when Israeli tanks fired shells at Gaza City on Saturday, killing four and injuring at least 25 people.

He passed away on Tuesday from his injuries, Ashraf al-Qidra, spokesman of Gaza's health ministry, told Ma'an. Hamas later claimed he was a fighter with the al-Qassam brigades.

Quno's death brings the total number of people killed in Gaza to seven since Saturday.

After Israel's shelling on Gaza City, factions fired dozens of rockets into Israel in response and Israel launched an airstrike early Sunday which killed two members of Islamic Jihad's military wing.

Israel launched multiple airstrikes on the Gaza Strip overnight Sunday, with no injuries reported, and 11 rockets have been fired from Gaza since Monday morning.

Warplanes struck three sites in Gaza overnight Monday in the fourth day of cross border violence. One rocket was fired overnight, an Israeli army spokesman said.
