The BBC's Middle East bureau chief Paul Danahar has tweeted:
I've heard no naval bombardment & no air strikes where I am in central #Gaza though perhaps they are elsewhere
Oh there you go, a distant air strike. So maybe it has been a 'relatively' quiet night after all
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.
