Deadly airstrikes pounded the Gaza Strip overnight as talks towards a truce between Israel and Hamas were set to resume in Cairo Sunday, AFP reports, citing Egyptian state television.

At least 75 people were killed overnight in new Israeli bombardment and ground combat, most of them women and children, according to the Gaza health ministry.

The fighting has raged on unabated despite a UN Security Council resolution last Monday that demanded an “immediate ceasefire” and the release of all hostages held by Hamas.

Tensions have risen over the spiralling civilian death toll between Israel and its chief backer the United States, especially over Israeli threats to push ground forces into Gaza’s crowded far-southern city of Rafah.

Washington has nonetheless approved billions of dollars worth of bombs and fighter jets for Israel in recent days, The Wall Street Journal reported, citing unnamed officials.
