Hizbullah announced Sunday morning on its al-Manar television station that it fired Raad-type rockets at Haifa. Eight people were killed and dozens injured in Haifa following the rocket attacks.
The terror group said it would not hesitate to attack the oil refineries in Haifa.
Hizbullah said that it fired dozens of Raad 2 and Raad 3 rockets at Haifa. "After the killing and destruction left by the enemy and after a long night of bombing in the southern quarter of Beirut and other areas in Lebanon and after ports and other infrastructures were attacked including a power station, the Islamic resistance (Hizbullah) has announced that it attacked with dozens of rockets, at exactly 9 a.m."
The al-Manar network has been broadcasting live pictures from Israeli television showing the extent of the attack on Haifa.
At the start of the campaign in Lebanon Hizbullah Secretary-General Hassan Nasrallah said he would not hesitate to fire long-range rockets at Haifa.
Hizbullah denied that it fired the Katyusha rockets that landed in Haifa on Thursday.
Its announcement Sunday is the first time Hizbullah said it was behind rockets on Haifa.
Security forces are preparing for the possibility that in response to an escalation of IDF activities in Lebanon, Hizbullah will try to fire rockets into the depth of Israel, beyond the frontline communities.
