Questions were tonight being asked about whether military equipment manufactured in the UK has been used in Israel's offensive on the Palestinian enclave.
Documents obtained by The Independent showed arms export licences worth £42 million were granted to 130 British defence manufacturers since 2010.
This allowed them to sell military equipment to Israel, ranging from weapons control and targeting systems to ammunition, drones and armoured vehicles.
The Government said it was now reviewing all licences to Israel.
At least 1,600 Palestinians - most of them civilians - have been killed and 8,000 injured during the assault, while Israel has lost 63 soldiers and three civilians.
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.
