Cameron urges end to Gaza crisis
A Downing Street spokeswoman said: "The Prime Minister expressed his sympathy for the unacceptable rocket attacks that Israel continued to suffer.
"He also expressed concern over the risk of the conflict escalating further and the danger of further civilian casualties on both sides.
"The Prime Minister said that the UK was putting pressure on both sides to de-escalate and urged Prime Minister Netanyahu to do everything possible to bring the conflict to an end."
It came after protesters gathered near the Israeli embassy in London to condemn the British Government's stance on the conflict.
