Israel mounts new strikes, Hamas ends attacks

The catalyst for the latest "cycle of violence" is in the last paragraph:

Hostilities first erupted when a blast on Friday killed 16 people at a Hamas rally in Gaza. Hamas blamed Israel and militants fired at least 40 rockets into the Jewish state in response, though Israel denied responsibility and the Palestinian Authority said it appeared to be an accident caused by Hamas members carrying explosives.

The Reuters scorecard:

Hamas:
> ends attacks
> said it would stop attacking the Jewish state
> said it was halting attacks
> announced his group's decision to halt attacks
> declares an end to its operations from the Gaza Strip
> would abide by a ceasefire declared in March
> blamed Israel [for the blast]

Israel:
> mounts new strikes
> launched multiple missile strikes in Gaza
> air raids
> attacked at least five targets across the Gaza Strip
> said it also attacked buildings used for making or storing weapons
> killed an Islamic Jihad leader in an air strike
> air strikes killed two Hamas militants
