JERUSALEM — Tel Aviv residents say they heard an explosion following an air-raid alert across the city, raising fears of a Gaza rocket strike on Israel's commercial capital.
Israeli authorities were trying to determine where the rocket may have landed on Thursday. Eli Bean, the head of Israel's rescue service, says no injuries have been reported.
Israeli military spokesman Brig. Gen. Yoav Mordechai says nothing landed on the ground, raising the possibility it fell in the sea.
A strike on Tel Aviv would be the first time Gaza rocket squads have reached the city and that would mark a significant escalation.
Israel has been threatening to widen a military offensive launched on Wednesday against Gaza militants.
