President Obama has spoken to Israeli Prime Minister Benjamin Netanyahu, Egyptian President Mursi by telephone about the rocket attacks from Gaza into Israel and violence in Gaza the White House has told Reuters.
Obama re-iterated to Netanyahu the US support for Israel's right to self defence and urged him to make every effort to avoid civilian casualties.
Netanyahu agreed that Hamas needs to stop its attacks on Israel to allow the situation to 'de-escalate.'
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.
