TEL AVIV (Reuters) -- Air raid sirens sounded in Tel Aviv on Friday and an explosion was heard, witnesses said, and Hamas militants in the Gaza Strip said they had fired a rocket at Israel's commercial center.
A police spokesman acknowledged an explosion had been heard but said there was no initial indication a rocket had struck the city nor any immediate reports of casualties or damage.
The armed wing of Hamas said it had fired a Qassam rocket at Tel Aviv.
Militants in Gaza launched two rockets toward the city on Thursday. The location of the impacts was not disclosed.
