Life in the Gaza Strip
Air raid sirens sounded across Tel Aviv metropolitan area on Thursday night for the first time since a 2014 war between Israel and militants in Gaza.An explosion was heard in the city centre. At first it was believed to have been from a rocket being shot down, but the Israel Defense Forces (IDF) said no rockets were intercepted and that it assumed they had landed in open areas.
Shortly after midnight, Israeli jets and helicopters attacked dozens of sites in Gaza belonging to Hamas and the Islamic Jihad group , Hamas sources said.The IDF subsequently announced that it had hit about 100 Hamas military targets, including an office complex in Gaza City allegedly used by the group to orchestrate attacks in the occupied West Bank, an underground facility that was the main manufacturing site of standard-grade rockets, and a military training site that served as a centre for unmanned aerial drones.According to Gazas health ministry, a man and a woman were seriously injured when a missile hit a house in the southern town of Rafah.Air raid sirens again rang out in Israeli towns close to Gaza overnight and on Friday morning, with the IDF saying several more projectiles had been launched.IDF spokesman Brig-Gen Ronen Manelis said the initial rocket fire had come as a "surprise", and that there had been no advance intelligence warnings.
But he stressed: "The Hamas organisation is the main organisation in the strip. It is responsible for what happens within the strip and what emanates from it."No militant groups have said they fired the rockets at Tel Aviv.Hamas insisted on Twitter that its armed wing was "not responsible", while the Hamas-run interior ministry in Gaza said the rocket fire went "against the national consensus" and vowed to take measures against the perpetrators.Hamas added that the rockets had been launched during a meeting with Egyptian mediators attempting to broker a long-term truce between Israel and Hamas.The organising committee of a months-long Palestinian protest campaign also announced that Fridays weekly demonstrations along Gazas border with Israel had been called off "in keeping with the public interest".
