The Israeli military said “a number of terrorists have infiltrated into Israeli territory”. Amateur videos posted on social media showed what appeared to be uniformed gunmen inside the Israeli border town of Sderot. The sound of gunfire could be heard in the videos, whose authenticity could not immediately be verified.

Sounds of outgoing rockets whooshing through the air could be heard in Gaza and sirens could be heard as far away as Tel Aviv, some 70 kilometres to the north, during the early morning barrage that lasted more than 30 minutes. Israel’s Magen David Adom rescue agency said a 70-year-old woman was critically injured when a rocket hit a building in southern Israel. Elsewhere, a 20-year-old man was moderately injured by rocket shrapnel, it said.
