Israel has carried out fresh attacks on Gaza and militants have launched more rockets into Israel as a hunt continues for a missing Israeli soldier. Palestinian officials said 50 people died overnight in Israeli strikes, most of them in Rafah, where the soldier, Hadar Goldin, went missing. A series of rocket attacks into Israel was reported on Saturday morning. At least 1,650 Palestinians, mostly civilians, and 63 Israelis, mainly soldiers, have died in the conflict. A Thai worker was also killed in Israel. Some 8,900 Palestinians have also been injured, the health ministry in Gaza says. A 72-hour ceasefire had been agreed, starting from Friday morning, but collapsed hours later. Hamas accused Israel of breaking the ceasefire but the Israel Defense Forces (IDF) said it had been forced to respond to militant rocket fire. US President Barack Obama on Friday described the crisis as "heartbreaking" and said he would work to secure another truce. Qassam Brigades' statement Palestinian officials said that there had been a series of Israeli air strikes around Rafah since midnight, killing at least 35 people. They said that across Gaza overnight, 40 homes, three mosques and a university were hit. Israeli media said that after a relatively quiet night, a number of rockets had been fired on Saturday morning, including at Tel Aviv.
