Foreign Secretary Lord David Cameron has called for an "urgent and transparent" investigation into the Israeli airstrike which killed three British aid workers, as he attends the NATO Summit in Brussels.

Lord Cameron told reporters: "I welcome what the Israeli foreign minister said yesterday to me about a full, urgent and transparent inquiry into how this dreadful event was allowed to happen. And we want to see that happen very, very quickly.

"I also welcome the fact that he spoke about much more aid getting into Gaza, up to 500 trucks a day. That is essential. We've been promised these things before and this really needs to happen, including longer opening times at the vital crossing points."
