DEIR AL-BALAH, Gaza Strip (AP) — Israeli airstrikes killed at least 26 people across the Gaza Strip on Thursday, hitting Hamas security officers and an Israeli-declared humanitarian zone.

As the daily bombardment continued, Israeli Prime Minister Benjamin Netanyahu’s office said he had authorized a delegation from the Mossad intelligence agency, the Shin Bet internal security agency and the military to continue negotiations in Qatar toward a ceasefire deal. Israeli media said the delegation would depart Friday.

There was no immediate Hamas comment. The U.S.-led talks have repeatedly stalled.

The Israeli strike in the seaside humanitarian zone known as Muwasi occurred as hundreds of thousands of displaced people are huddling there in damp winter weather.

“Everyone was taking shelter in their tents from the cold, and suddenly we found the world turning upside down. Why, and for what?” said Ziyad Abu Jabal, displaced from Gaza City.

The early morning strike killed at least 10 people, including three children and two senior Hamas police officers.

Israel’s military said it targeted a senior officer in the Hamas-run police force. It said he was involved in gathering intelligence used by Hamas’ armed wing in attacks on Israeli forces.

Another Israeli strike killed at least eight Palestinians in Deir al-Balah in central Gaza. The men were members of local committees that help secure aid convoys, according to Al-Aqsa Martyrs Hospital, which received the bodies. An Associated Press reporter there confirmed the toll.

There was no immediate comment from the Israeli military on the strike.

In southern Gaza, Israel’s military killed five policemen in eastern Khan Younis. Israeli government spokesman David Mencer said the strike targeted the head of the Hamas internal security force in southern Gaza.

“Where did we find him? Where else, but of course hiding in the humanitarian zone in Khan Younis, where Gazans are sheltering from this war,” Mencer said.
