A car bomb has exploded in a Hezbollah stronghold near Lebanon's northern border with Syria, killing at least three people, officials say.
The blast happened near a petrol station in the eastern town of Hermel in the Bekaa Valley, state media said.
A group calling itself the al-Nusra Front in Lebanon claimed it had carried out the attack.
