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.

Israel’s military said a “technical error” had caused munition to land dozens of meters from its target. The victims were gathered near a water distribution point, health workers said.

Israel and Hamas appeared no closer to a breakthrough in indirect talks meant to pause the war and free some Israeli hostages after Prime Minister Benjamin Netanyahu’s Washington visit last week.
