Four killed in Israeli attacks in Gaza, including two children

The Israeli military has not commented on any individual attack but says the military "struck several Hamas infrastructures during the night."

A fragile ceasefire has been in place between Israel and Hamas, which is branded a terrorist group, since October last year. Since then, more than 1,000 Palestinians have been killed in Gaza, according to Hamas-controlled authorities.

Israel says it is continuing to fight the extremist movement Hamas and has expanded the area under military control.
