Clashes and recriminations have threatened to torpedo the existing deal, Reuters reports.

A Palestinian source has said up to 100 hostages could ultimately go free. Qatar, Egypt and the United States are pressing for the truce to be extended beyond Monday but it is not clear whether that will happen.

The killing of a Palestinian farmer in the central Gaza Strip had earlier added to those concerns. The farmer was killed when targeted by Israeli forces east of Gaza’s long-established Maghazi refugee camp, the Palestinian Red Crescent said.

The armed wing of Hamas also said on Sunday that four of its military commanders in the Gaza Strip had been killed, including the commander of the North Gaza brigade, Ahmad Al Ghandour. It did not say when they had been killed.

Violence has also flared in the West Bank, where Israeli forces killed seven Palestinians, including two minors and at least one gunman over the weekend, medics and local sources said.
