It has increased the pressure on Israel to fulfill its legal responsibilities to protect Palestinian civilians, and to allow adequate supplies of humanitarian aid to reach the people who need it.

Mr Türk, who is the UN high commissioner for human rights, said that if intent was proven, that would amount to a war crime.
