The Foreign Secretary, William Hague, says Egypt is making "strong efforts" to bring about a ceasefire between Israel and Gaza.
Speaking in Brussels Mr Hague said a clear message was also needed from the whole of the European Union to bring an end to the violence.
Today's bombing in Tel Aviv is reminiscent of six years ago and could mark a serious escalation in the conflict.
A truce in Gaza suits all sides but none of the groups seem interested in a long-lasting solution.
A complex system of air defences has been instrumental in protecting Israel's population from incoming rockets.
