DEIR AL-BALAH, Gaza Strip (AP) — The Israeli military renewed warnings on Monday for Palestinians in Gaza not to return to the embattled territory’s north, a day after Gaza hospital officials said five people were killed as throngs of displaced residents tried to reach their homes in the war-torn area.

Northern Gaza was an early target of Israel’s war against Hamas and vast parts of it have been flattened, forcing much of the area’s population to flee south. While around 250,000 people are said to be living in the north, the Israeli military has prevented most displaced people from returning throughout the six-month-long war, saying the area is an active battle zone.

The military has reduced the number of troops it has in Gaza and has said it has loosened Hamas’ control over the north, but Israel is still carrying out airstrikes and targeted operations in the area against what it says are reorganizing militants, most prominently at Gaza’s main hospital, Shifa, which is in ruins after a two-week raid and fighting last month.
