BEIRUT, March 16 (Xinhua) -- At least four people were killed and seven others wounded when a suicide bomber exploded his car on Sunday night in the Nabi Othman town in the Bekaa region in eastern Lebanon, the National News Agency reported.
According to the report, a car exploded near a gas station on the main road of Nabi Othman, killing four people and wounding seven others. Initial investigation showed that the explosives used in the suicide attack weigh around 20 kilograms.
The Al-Nusra front in Lebanon claimed responsibility of the suicide attack, refuting the claim previously made by the "Free Sunni Battalion," a fundamentalist Sunni group that said it carried out the attack in retaliation for "the Hezbollah involvement in Syria," the National News Agency reported.
The Al-Nusra front, an al-Qaida-linked terrorist organization, said it has "warned the Iran-linked party in Lebanon that it will pay the price for its aggression against the Sunnis and for fighting in support of the regime of Syrian President Bashar Assad. "
In eastern Lebanon, which is dominated by Hezbollah, deadly suicide bombing attacks were seen since the armed movement voiced support for the Syrian government in the three-year war against rebels.
This is the fourth suicide attack in the Bekaa region which is considered as the heartland of Hezbollah.
