Two rockets were fired from the Gaza Strip in the direction of the greater Tel Aviv area on Friday afternoon prompting a red alert air raid siren to be sounded in the city for the second straight day.
Defense officials gave no immediate word of a rocket being located. Local residents reported hearing an explosion following the siren. No injuries or damage were reported.
The armed wing of Hamas claimed responsibility for the attack.
Thursday's attacks on the Tel Aviv area marked the first time the center of the country was hit in the renewed violence from the Gaza Strip and the first time that a real siren was sounded in Tel Aviv since the Gulf War in the early 1990s. Palestinian Islamic Jihad took responsibility for Thursday's rocket on Tel Aviv.
More than 350 rockets have landed in Israel since the operation began on Wednesday, with three Israeli losing their lives in a rocket attack on Kiryat Malachi on Thursday.
The IDF has struck some 500 terror targets in Gaza since the operation began. According to Palestinian sources 20 people have been killed in IDF strikes on Gaza.
The attack on the greater Tel Aviv area came as Operation Pillar of Defense entered its third day. Some 70 rockets fell in the South of Israel on Friday morning despite the IDF's continued air strikes on Gaza, meant to root out the terror infrastructure in the territory.
