The Israeli air strike that has killed a Hamas military chief heralds a dangerous period for Israel.
It is the first such murder for four years and proof the "war" never ended.
Why now? Why light a fire it surely doesn't need amid Arab chaos and an ongoing Iran issue.
Commander Ahmed Al-Jaabari has been high on Israel's kill list for a decade but the Shin Bet security service and the government must have a solid reason to do it now. It's a gamble.
Israel's army says it killed the Hamas chief to "severely impair the command and control chain of leadership". Al-Jaabari was directly responsible for terror attacks in past years.
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.
