The European Union’s ambassador to Israel, Emanuele Giaufret, sharply criticized the rocket attacks on Twitter, saying “firing indiscriminately against civilians (is) unacceptable.”
Israeli officials said a 50-year-old woman was severely wounded by rocket fire, while a teenage boy was mildly hurt as he ran for cover.
Gaza’s Health Ministry said a Palestinian infant was killed in an Israeli airstrike.
Leaders of the two groups were in Egypt for talks with mediators aimed at restoring a fraying cease-fire. Hamas leaders have hoped the recent calm would pave the way for a deeper, longer-term cease-fire.
The Israeli military accused the Iranian-backed Islamic Jihad of instigating this round of violence by shooting and wounding two Israeli soldiers Friday. It said the shooting was not coordinated with Hamas, but blamed the movement for the flare-up in its capacity as the territory’s rulers.
