Sleiman said on Wednesday that Lebanese political parties should take measures against the shipment of arms and militants into Syria and the establishment of training bases for the militants in Lebanon.

He stressed that Beirut was committed to the policy of non-interference in the internal affairs of Syria, as well as strengthening its own national unity.

The comments came after two radical Lebanese clerics called on people to join the foreign-sponsored militant groups in Syria to help topple the government of President Bashar al-Assad.

Sleiman has on numerous occasions voiced opposition to military intervention in Syria. Instead, he has called for international support for dialogue to resolve the crisis that has gripped Syria for over two years.

Over the past months, the foreign-sponsored militant groups have made several attempts to infiltrate into Syria through Lebanon’s border. Damascus has called on Beirut to stop the flow of arms and militants into Syria.

The Syrian government says the chaos in the country is being orchestrated from outside.

President Assad has said that if the militant groups take power in Syria, they could destabilize the entire Middle East for decades.
