Air strikes by the Israeli army since Tuesday have killed fighters as well as civilians, including several children, said officials in the crowded coastal territory. ADVERTISEMENTRocket fire from Gaza killed one person in the central Israeli city of Rehovot and injured at least two others, Israeli police said. Cairo mediated in efforts toward a truce between Israel and the Islamic Jihad militant group, while the European Union called for an immediate ceasefire. Miriam Keren, 78, an Ashkelon resident, said a Gaza rocket had destroyed a workshop and damaged her house. Both Hamas, which rules Gaza, and Islamic Jihad are considered terrorist groups by Israel and the United States.
