Bodies of Palestinians killed in an Israeli airstrike in central Gaza arrived at Al Aqsa hospital in Deir al-Balah.

An Israeli airstrike killed at least six Palestinians in central Gaza, health officials said.

It hit a makeshift coffee house on the coastal side of Zawaida town, according to Gaza’s Health Ministry, part of the Hamas-run government.

Another Israeli strike killed at least two people near the Al-Ahly soccer club in the Nuseirat refugee camp, the ministry said.

The strike hit a tent and wounded eight others, said Awda hospital, which received the casualties.

A third strike hit a tent in the Muwasi area of Khan Younis in the south, killing at least one person, according to Nasser Hospital.

An Israeli military official told journalists there had been three incidents Sunday, two in southern Gaza and one in the north, and noted that the update was partial for now.

Israel on Sunday struck targets in southern Gaza after saying its troops came under fire from Hamas militants, in the first major test of a U.S.-brokered ceasefire meant to halt more than two years of war. Health officials said at least nine Palestinians were killed.

A senior Egyptian official involved in the ceasefire negotiations said “round-the-clock” contacts were underway to deescalate the situation.

The official spoke on condition of anonymity because he wasn’t authorized to speak to reporters.

Israeli Prime Minister Benjamin Netanyahu directed the military to take “strong action” against any ceasefire violations but didn't threaten to return to war.

Israel's military said that militants fired at troops in areas of Rafah city that are Israeli-controlled according to agreed-upon ceasefire lines.

No injuries were reported. The military said Israel responded with airstrikes and artillery.

Hamas, which continued to accuse Israel of multiple ceasefire violations, said communication with its remaining units in Rafah had been cut off for months and “we are not responsible for any incidents occurring in those areas.”

The Palestinian group also said that talks to launch the second phase of ceasefire negotiations have begun.
