Several children were killed in an Israeli airstrike at a water distribution point in central Gaza Sunday, health officials said, one of several deadly incidents in the territory that come as ceasefire talks in Doha falter.

Several people have been killed at a Gaza Strip water distribution site in an Israeli attack that the military says was meant for a different target but fell dozens of metres short. Local officials say most of the eight Palestinians killed were children.

Senior Palestinian officials accuse Israel of deliberately stalling the negotiations in Qatar during the prime minister's US visit.
