A humanitarian crisis is unfolding in Gaza, where more than 1,100 people have been killed by Israeli airstrikes.
Israel has formed an emergency government and war cabinet in the wake of Hamas' attacks on border communities, which have killed at least 1,200 people and injured thousands more.
At least 150 hostages seized by Hamas gunmen are being held at secret locations inside Gaza - among them are women, children and the elderly.
In Gaza, the only power station has shut down after running out of fuel.
Israel has cut off electricity supplies to the region, as well as access to medicines, food, fuel and water.
