Syria's air force on Thursday carried out fresh strikes on areas on the outskirts of the northeastern border town of Arsal.Voice of Lebanon radio (93.3) said Syrian warplanes carried out eight raids in two stages on Khirbet Younin on the outskirts of Arsal at noon, targeting Syrian opposition fighters.
A similar attack was made on Wadi Ajram on Thursday morning.
The new raids came after an assault on Wednesday night.
"Syrian helicopters carried out two strikes against the areas of Wadi Ajram and Khirbet Younin on the outskirts of Arsal, just after 9:00 pm" on Wednesday, said a Lebanese security official.
"The strikes caused no injuries," he told Agence France Presse.
The official said the strikes may have been targeting rebels fleeing the Qalamoun area where Syria's forces are on the offensive.
Syria's army and Hizbullah overran the rebel bastion Yabrud in the Qalamoun mountains on Sunday and are now targeting other opposition strongholds along the frontier with Lebanon.
Mainly-Sunni Arsal has been periodically targeted with often deadly air strikes by Syria's forces in the past few months.
Arsal's residents support the Syrian revolt against President Bashar Assad, and the town is hosting tens of thousands of Syrian refugees.
Smuggling routes used by opposition forces to move fighters and weapons back and forth between Lebanon and Syria pass through the Arsal area.
The state-run National News Agency said the army on Wednesday arrested 15 Syrian men at a checkpoint in Arsal.
"The men had entered Lebanese territory with forged papers, and some of them were members of (Syria's al-Qaida affiliate) al-Nusra Front."
