Israeli strikes in the Gaza Strip killed at least 32 people on Sunday, including six children at a water collection point, while the Palestinian death toll passed 58,000 after 21 months of war, local health officials said.

Gaza's civil defence agency said Israeli air strikes on Sunday killed more than 40 Palestinians, including at a market and a water distribution point, as talks for a ceasefire between Israel and Hamas stalled.

Ten people, including six children, have been killed in an Israeli air strike while waiting to fill water containers in central Gaza on Sunday, emergency service officials say.
