Israeli tank shells killed 4 Palestinians and wounded 30 in the Gaza Strip on Saturday, medics and witnesses said. Ahmad al-Dardasawi, 18, and Muhammad Hararah, 17, were killed in Gaza City, and two unidentified men later died from injuries sustained in the attack. At least 26 people were wounded in the shelling, with 10 said to be in a serious condition, according to Palestinian Ma’an News Agency. Residents said a crowded mourning tent in the al-Shujaiyeh neighborhood near Gaza City was full of people paying respects to a bereaved family man when a shell struck. Four people were also wounded in Khan Younis as Israel’s army targeted an area east of city, witnesses said. “The occupation’s targeting of civilians was a grave escalation that must not pass in silence,” said Hamas spokesman Fawzi Barhoum. “Resistance must be reinforced in order to block the aggression.”
