Israeli forces launch fresh Gaza offensive

Window for peace remains narrow, say experts, as concern aired over rising toll

The window for lasting peace in the Gaza Strip remains perilously narrow, experts warn, as Israel launched a large-scale military operation on Saturday, despite mediators' efforts for ceasefire talks.

Israeli airstrikes killed at least 100 Palestinians across Gaza overnight, health authorities said on Sunday.

There was no immediate comment from the Israeli military, which has expanded its strikes on the enclave, killing hundreds of people since Thursday. It has said the expansion is aimed at "achieving all the war's objectives", including release of hostages and "the defeat of Hamas".
