Israel's vaunted Iron Dome anti-missile system on Sunday shot down two rockets over Tel Aviv as sirens wailed across the city, in the fourth such interception in one day, police said.

"Sirens sounded in Tel Aviv, and the Iron Dome shot down two rockets," said police spokesman Micky Rosenfeld.

"There were no reports of injuries or damage on ground level in Tel Aviv or (the surrounding region of) Gush Dan," he added.

Sunday was the fourth straight day sirens sounded across Tel Aviv. Earlier in the day, Israeli police confirmed two rockets had been intercepted over the city by Iron Dome.

Hamas's armed wing, the Ezzedine al-Qassam Brigades, said they launched a Fajr-5 rocket at Tel Aviv in response to the "occupation's massacre."

Earlier on Sunday, at least seven members of the same family, four of them children, were among nine people killed when an Israeli missile destroyed a family home in Gaza City.

Iranian-made Fajr 5 rockets have a range of up to 75 kilometres (46 miles).

On Thursday, Hamas said it had developed its own longer-range rocket, the M75, which was used to target Jerusalem.
