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

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.

At least six children were killed in an Israeli strike on a water collection point. The Israeli military blamed a technical error which made its munition fall "dozens of meters from the target".
