A rocket fired from the Gaza Strip was intercepted over the Israeli coastal city of Tel Aviv on Thursday morning, the military said.
A spokesman earlier told AFP that two rockets had been intercepted by Israel's Iron Dome anti-missile system, but subsequently revised the number down.
In the Gaza Strip, where Israel has been carrying out a widespread aerial campaign, the armed wing of the Hamas movement announced it had fired two M75 rockets at Tel Aviv.
"The Qassam Brigades struck Tel Aviv with two M75 rockets," the Ezzedine Al-Qassam Brigades said in a statement.
The locally-produced M75 rocket has a range of about 80 kilometres (50 miles), able to reach Tel Aviv, which lies around 70 kilometres from the Gaza Strip.
