The Israeli port city of Tel Aviv was on alert for a possible rocket attack after Hezbollah leader Hassan Nasrallah threatened to fire rockets into the city, local media reported on Friday.

The municipality has begun organizing shelters and special reinforced areas in Israel's second largest city.

Emergency team practiced to deal with the situation that rockets were to fall in Tel Aviv.

The city's website provides maps of location of public shelters.

On Thursday, Nasrallah said in a taped television speech that if Israel bombed the Lebanese capital Beirut, Hezbollah would bomb Tel Aviv.
