Israeli tanks thrust deeper into two north Gaza towns and a historic refugee camp, trapping around 100,000 civilians, the Palestinian emergency service said, in what the military said were operations to root out regrouping Hamas fighters.

The Israeli military said soldiers captured around 100 suspected Hamas militants in a raid into Kamal Adwan hospital in the Jabalia camp. Hamas and medics have denied any militant presence at the hospital.

The Gaza Strip’s health ministry said at least 19 people were killed by Israeli airstrikes and bombardment on Monday, 13 of them in the north of the shattered coastal territory.

The Palestinian Civil Emergency Service said around 100,000 people were marooned in Jabalia, Beit Lahiya and Beit Hanoun without medical or food supplies. Reuters could not verify the number independently.
