In a telephone conversation with Egyptian President Mohammed Mursi, President Obama condemned the rocket fire from Gaza to Israel.
President Mursi agreed on the importance of working to de-escalate the situation with Israel and Gaza as quickly as possible.
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.
