At 2 A.M. on Thursday night, the sounds of explosions echoed from east to west. Thousands of East Jerusalem residents came out to celebrate what they perceived as a Hamas victory in the latest round of fighting with Israel. The celebrations included marches, honking of car horns and dozens of firecrackers shot into the night sky. Under cover of the quiet night, the sounds of the explosions reached all parts of the city. Residents of the westernmost parts of Jerusalem said they were woken up by the sounds. It was just the first of a series of events in East Jerusalem during the weekend that attest that the cycle of violence, which began in the city 40 days ago, and spread to Gaza, Lod and Jaffa – and has returned to reverberate in Jerusalem.
