“We promise the Hizbullah members who are deployed in Syria that they will face a severe and earthshaking retaliation over their interference in the Syrian affairs and aiding the regime of President Bashar Assad to kill the Syrian people,” the Joint Command of the Free Syrian Army in Syria said in a statement.

In the statement, the FSA also promised Hizbullah chief Sayyed Hassan Nasrallah “surprises that will deprive him of sleep.”

“We call on our Lebanese brothers – who belong to a certain religious community and who have strayed and believed the lies of the devil, Khamenei’s agent in Lebanon – to return to the path of right before it’s too late and not to let your siblings become the fuel of a war you are not part of,” the FSA added.

“Do not deprive yourselves of the lung you are breathing through and of your only land route in the region,” the FSA went on to say, addressing Hizbullah’s supporters.

A Hizbullah commander and several fighters have been killed inside Syria, a Lebanese security official told the Associated Press on Tuesday.
