The US Congress has rushed through a $225 million (£134m) bill to support Israel's missile defence system.
The money will help restock Israel's Iron Dome, which has been credited with shooting down dozens of incoming rockets fired by Palestinian militants since July 8.
President Barack Obama has said the Iron Dome is a concrete way the US was helping "make sure that Israel is able to protect its citizens".
There have been two days of quiet in Gaza. No rockets or missiles, no more destroyed houses, no more ambulance sirens screaming.
A three-year-old girl has been rescued from Gaza and brought to London for life-saving heart surgery.
A small team of NHS doctors and surgeons is travel to Gaza to set up facilities and establish how best to use specialists and equipment.
