Hamas sources in Gaza say 18 people suspected of collaborating with Israel have been executed.

The killings came after an Israeli air strike killed three senior Hamas leaders on Thursday. Four more Palestinians died in overnight strikes and on Friday.

Meanwhile, a four-year-old boy has been killed in a mortar attack on a southern Israeli village along the Gaza border.

More than 2,070 Palestinians, mostly civilians - among them more than 400 children - and 68 Israelis have been killed in recent weeks.
