BBC reporting:

Israeli warplanes have bombed what the army says is a Palestinian militant base in Lebanon hours after rocket attacks on two Israeli border towns.

They struck at a target south of the capital, Beirut, which was described as a base of the Popular Front for the Liberation of Palestine.

There was no immediate information on casualties or damage.

“This is in response to the firing of projectile rockets last night toward Israeli communities,” the army said.

At least four rockets fired from Lebanese territory hit Israeli towns close to the border on Tuesday evening without causing casualties.

No group claimed responsibility for the rocket attack. Both Hezbollah guerrillas and Palestinian militants operate in nearby southern Lebanon.

In Wednesday’s raid, Lebanese witnesses reported warplanes roared over the Syrian-backed group’s base, a maze of concrete fortified tunnels built inside a hill that the group has used as a base for decades. At least two explosions were heard.

Other witnesses said two air-to-surface missiles were fired at the planes.

Lebanese troops at a checkpoint confirmed an air raid and sealed off the area, preventing journalists from approaching.

The raid came a month after Israeli jets attacked a command post of the Hezbollah guerrilla group in south Lebanon, responding to Hezbollah rocket and mortar attacks that wounded 11 Israeli soldiers and damaged a house in a border community.

Israel withdrew from an occupied enclave in southern Lebanon in 2000. While fighting in the area has dropped since then, the border remains tense and Hezbollah frequently targets Israeli troops in the disputed Chebaa Farms area.
