Israeli tanks pushed back into parts of the northern Gaza Strip Tuesday which they had left weeks ago, while warplanes conducted air strikes on Rafah, the Palestinians' last refuge in the south of the territory, killing and wounding several people, medics and residents said.

Tanks advanced into Beit Hanoun and surrounded some schools where displaced families have taken refuge..

Beit Hanoun, home to 60,000 people, was one of the first areas targeted by Israel's ground offensive in Gaza last October.

Many families who had returned to Beit Hanoun and Jabalia in recent weeks after Israeli forces withdrew, began moving out again because of the new raid, some residents said.

Palestinian health officials said an Israeli strike had killed four people and wounded several others in Rafah, where over half of Gaza's 2.3mn people are sheltering and bracing for a planned Israeli ground offensive into the city, which borders Egypt.

Palestinian health officials and Hamas media said an Israeli air strike had killed 11 Palestinians, including children, in the Al-Maghazi refugee camp in the central Gaza Strip.

The Palestinian health ministry said more than 33,000 Palestinians have so far been killed by Israeli fire since Oct. 7, including 46 in the past 24 hours.

The Hamas-run interior ministry also said an Israeli air strike had hit a police car in the Tuffah district of Gaza City, killing four police officers and three civilian passers-by.

After six months of fighting, there is still no sign of any breakthrough in US-backed talks led by Qatar and Egypt to clinch a ceasefire deal in Gaza, as Israel and Hamas stick to their mutually irreconcilable conditions.

The Israeli military said its forces continued to operate in the central Gaza Strip and that they had killed several gunmen who attempted to attack them.

In Al-Nusseirat refugee camp in the central Gaza Strip, residents said Israeli planes had bombed and destroyed four multi-storey residential buildings.

Israel is still imposing "unlawful" restrictions on humanitarian relief for Gaza, the U.N. human rights office said, despite assertions from Israel and others that barriers have eased.

Israel is under international pressure to allow more aid into Gaza, especially northern areas where famine is expected by May, according to the United Nations.
