By Nidal al-Mughrabi CAIRO (Reuters) -Israeli tanks pushed into southern and eastern areas of the Gazan city of Deir Al-Balah for the first time on Monday, an area where Israeli sources said the military believes some of the remaining hostages may be being held.

The co-founder of a pro-Palestinian campaign group sought on Monday to challenge the British government's decision to ban the group under anti-terrorism laws, a move her lawyers said had "the hallmarks of an authoritarian and blatant abuse of power".

The city is packed with thousands of displaced people - it's also believed Israeli hostages are being held in the area.

Razan was one of at least four children to succumb in the last three days, the youngest just three months. Over the past 24 hours, 18 deaths have been recorded due to famine in Gaza, the health ministry says, reflecting a deepening crisis in the territory.
