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 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.
