Egypt's Foreign Minister will visit Gaza tomorrow as the country tries to broker a ceasefire between Israel and Palestinian militant groups.
The Egyptian government said:
"Mohamed Amr will head to Gaza accompanying an Arab ministerial delegation to express solidarity with the brave Palestinian people who are subjected to Israeli aggression for the sixth day in a row."
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.
