Several militants have kidnapped a Lebanese man in the northeastern border town of Arsal and taken him to its outskirts, the state-run National News Agency reported on Tuesday.
The assailants from the extremist Islamic State group abducted on Monday night Younes al-Hujeiri in the area of Wadi Hmeid, said NNA.
The agency said the authorities have no information about his fate.
IS and al-Qaida-linked al-Nusra Front militants are hiding in the mountains on the porous border area between Lebanon and Syria.
In August, they overran Arsal and engaged in bloody gunbattles with the Lebanese army.
The fighters took with them hostages from the military and police and later executed four of them.
There are ongoing negotiations to release the captives.
