What is going on between Israel and the Palestinians?
Hamas militants have launched dozens of rockets at Israel after Israeli air strikes killed senior commanders and felled a multi-storey building in Gaza.
The escalation of the fighting, which began on Monday, has prompted the UN to warn of a "full-scale war".
At least 65 people in Gaza, including 14 children, and seven people in Israel have been killed since then.
