UN Secretary-General Antonio Guterres called Monday for an "immediate humanitarian ceasefire" in the Gaza Strip, as the fighting between Israel and Hamas passed the 100-day milestone.

 "We need an immediate humanitarian ceasefire. To ensure sufficient aid gets to where it is needed.

To facilitate the release of the hostages. To tamp down the flames of wider war because the longer the conflict in Gaza continues, the greater the risk of escalation and miscalculation," Guterres said at a press briefing in New York.
