( CNN ) -- Lebanon has released Chadi Mawlawi , an activist who was helping Syrian refugees and whose arrest sparked fighting in Lebanon . The military investigating judge approved Mawlawi 's release on bail , the Lebanese state-run news agency NNA reported Tuesday . Fighting has been under way in parts of Lebanon , including suburbs of Tripoli , in what analysts describe as an extension of the unrest in neighboring Syria . Mawlawi , an Islamist activist , was supporting Syrian rebels and trying to help refugees in Lebanon by providing shelter and food when he was arrested , one of his cousins said . Lebanon accused Mawlawi of being an operative in an al Qaeda-inspired group -- something his relatives deny . Nadim Shehadi , associate fellow of the Middle East and North Africa program at the London think tank Chatham House , said Lebanon is seeking neutrality and wants to avoid spillover from the Syrian violence . But `` that 's an impossible objective to attain because if you help the refugees , you 're supporting the revolution , and if you do n't help the revolution , you 're supporting the regime . '' Violence in Lebanon has spread in recent days . Two clerics opposed to Syrian President Bashar al-Assad were killed Monday at a military checkpoint in northern Lebanon . The deaths sparked clashes between rival political parties -- one supporting al-Assad and the other opposing him -- that left two other people dead and 18 wounded in Beirut , according to the state-run news agency . Derek Plumbly , the United Nations ' special coordinator for Lebanon , called for an end to the violence and said the incidents must be `` thoroughly investigated . '' And U.S. State Department spokesman Mark Toner said the United States is `` concerned by the security situation . ''
