Israeli airstrikes killed at least 38 Palestinians in Gaza, hospital officials told the Associated Press on Sunday, as Israel's military said it has struck over 100 targets in the embattled enclave in the past day.

Explosions lit up the night sky over the Gaza Strip in a fiery orange glow, as fighting between Israel and Hamas continued.

An Israeli strike hit Palestinians near a medical centre in Gaza on Thursday, killing 16 including children and wounding more people, local health authorities said, as ceasefire talks dragged on with no result expected soon.
