Israeli forces intensified their retaliative attacks in Lebanon Thursday and brought the death toll to 55 civilians.

Israeli army is imposing a comprehensive blockade on Lebanese air, sea and land in a response to Hizbollah's capture of two Israeli soldiers on Wednesday morning.

A total of 55 Lebanese civilians, including children, were killed in Israeli raids cross the country on Thursday, Hizbollah's television channel al-Manar reported.

At Thursday morning, Israeli aircraft bombed runways at Rafik Hariri International Airport, the country's only international airport, forcing flights to divert to Cyprus.

Later in the day, Israeli aircraft also attacked two military airbases and gunboats fired shells at fuel tanks at Beirut airport, witnesses said.

The Hizbullah's Al-Manar television station in the group's stronghold in Beirut's southern suburb also hit by Israeli missile on Thursday, wounding six people.

Meanwhile, Israeli Planes dropped leaflets in a Beirut suburb, urging residents to stay away from Hizbollah offices, witnesses said.

In order to retaliate for Israeli "massacres", Hizbollah fired about 60 Katyusha rockets at Nahariya in northern Israel on Thursday, killing a civilian and 21 others, al-Manar reported.

Israeli security sources said two Katyusha rockets fired from Lebanon hit Israel's third largest city of Haifa Thursday evening, while Lebanese Hezbollah denied launching rockets at the city.
