The UN Secretary-General says the bus bombing in Tel Aviv underscores the need for an immediate Gaza ceasefire. Ban Ki-moon added:
I am particularly concerned about the spiral of violence at the time of intense efforts to reach a ceasefire in Gaza and Israel... We all know there are many details to work out. But while that happens civilians continue to die.
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.
