Gaza (CNN) — An Israeli delegation has been ordered home from talks in Cairo aimed at ending the conflict in Gaza, a senior Israeli official said Tuesday, shortly after the Israeli military blamed militants in Gaza for breaking a truce.

Three rockets fired from Gaza hit the Beer Sheva area in southern Israel Tuesday afternoon, the Israeli military said. No injuries were reported.

The rocket fire came only hours after the ceasefire was extended until the end of the day, as Palestinian and Israeli negotiators, struggling to reach a more lasting agreement, reported little progress.
