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.

Gaza health officials say Israeli airstrikes have killed at least 19 people including six children at a water collection point.

Israeli officials said on Tuesday that gaps can be bridged between Israel and Palestinian militant group Hamas at peace talks in Qatar, though it may take more than a few days to reach a deal to free hostages and halt fighting.
