A suicide bomber killed himself and at least three soldiers when he detonated a car bomb at a Lebanese army checkpoint in the border town of Ersal on Saturday, Lebanese media said.
The Lebanese National News Agency reported that at least four soldiers were wounded in the blast.
“A suicide bomber detonated his car in front of a Lebanese army checkpoint at Aqabet al-Jurd in the Arsal area,” an official told AFP.
“There were at least seven soldiers at the checkpoint,” the official added.
The attack was claimed on Twitter by a little-known group calling itself Liwa Ahrar al-Sunna in Baalbek – Arabic for the Brigades of the free Sunnis.
“The next few days will see several jihadis and blessed attacks like this one. This is only the beginning,” the group said, adding that the army would be among its targets.
It said the attack was to avenge the death of Sami al-Atrash, a suspect wanted in connection with car bombings.
Atrash was killed during a Lebanese army raid on his house in Ersal on Thursday.
Liwa Ahrar al-Sunna also claimed a March 16 car bombing in eastern Lebanon that killed two people.
The same attack was also claimed by Al-Nusra Front, Al-Qaeda’s Syria affiliate, with both groups saying it was in revenge for the fall of Yabrud.
The explosives-laden car used on Saturday evening was a black Kia, the NNA reported.
Security forces cordoned off the area as rescue teams arrived on the site of the attack by military helicopter, due to its remote location.
Residents of the eastern city of Baalbeck cut off the highway to the northern Bekaa Valley and burned tired in solidarity with the army to condemn the blast, the NNA added.
On Saturday, the army made further raids in Ersal, where they have set up checkpoints this month.
Lebanon has endured numerous rocket and bomb attacks since the escalation of the Syrian conflict.
