The attacks were the latest Israeli violations of the ceasefire and prisoner exchange agreement that took hold in Gaza in January, halting Israel’s brutal war, which has killed over 48,500 Palestinians, most of them women and children, and left the enclave in ruins.

An Israeli air strike killed four Palestinians in Gaza on Tuesday, the territory's civil emergency service said, as Arab mediators and the United States tried to hammer out differences between Hamas and Israel over a January 19 ceasefire agreement.

The latest deaths brought the overall Palestinian death toll from the war to 48,503. More than 110,000 people have been wounded, according to the Gaza Health Ministry.

Two Palestinians were killed and several others wounded in Israeli artillery shelling in the Gaza Strip on Sunday despite a ceasefire agreement, medics said. Eyewitnesses said Israeli forces stationed along Gaza’s eastern border fired a shell at a Palestinian crowd in the Sujaiya neighborhood in Gaza City.

The head of Gaza’s government media office, accused Israel of deliberately intensifying its attacks on Palestinians over the past 10 days in violation of the ceasefire deal.

Israeli fire has killed eight Palestinians in the Gaza Strip and three more in the occupied West Bank over the past 24 hours, Palestinian officials said Tuesday, even as a fragile ceasefire with Hamas in Gaza has largely held since late January.
