Israeli airstrikes on southern Gaza kill nearly 15 people overnight

Israeli strikes in the southern Gaza Strip killed at least 15 people overnight, including six children and two women, Palestinian medical officials said on Tuesday.

In northern Gaza, where Israel has been waging an air and ground campaign in Jabaliya for more than a week, residents said families were still trapped in their homes and shelters.

It's been more than a year since Hamas-led militants blew holes in Israel's security fence and stormed in, killing some 1,200 people, mostly civilians, and abducting another 250. They are still holding about 100 people captive inside Gaza, a third of whom are believed to be dead.

Israel's offensive in Gaza has killed over 42,000 Palestinians, according to local health authorities, who do not say how many were fighters but say women and children make up more than half of the fatalities. The war has destroyed large areas of Gaza and displaced about 90 per cent of its population of 2.3 million people.
