A car bomb exploded at dawn Tuesday in eastern Lebanon near a Hezbollah position, according to Agence France-Presse.
"A blast went off at around 4:00 am (0200 GMT)... near a Hezbollah position in Sbouba... causing deaths and injuries," an anonymous security source told AFP. The source added that the attack was caused by a car bomb.
It is not yet clear how many casualties have resulted from the explosion.
Immediately following the explosion, Hezbollah as well as Lebanese security forces were deployed to the scene.
Hezbollah-controlled areas and convoys have been targeted in recent months throughout the country, particularly in Beirut and the Bekaa valley in eastern Lebanon. Analysts, for example, believe the Nov. 19 bomb attack on the Iranian embassy that killed 23 people is linked to Tehran's support of Shi'ite Hezbollah in Syria's war.
