Free Syrian Army spokesperson Louay al-Moqdad said that the Lebanese Shiite group Hezbollah has been coordinating with the Syrian army and is now waging ground offensives inside Syria.
“For the first time [Hezbollah] is conducting ground offensives [in Qusayr] with the help of the arsenal stationed in Syrian villages and Lebanese border-towns that are under its control,” Moqdad said in remarks published by An-Nahar newspaper on Monday.
He added that the military operations of Hezbollah were lead by two of its officials, Mustafa Badreddine Din and Wafiq Safa.
Badreddine was indicted by the Special Tribunal for Lebanon for involvement in the 2005 assassination of former Lebanese Prime Minister Rafiq Hariri.
On Sunday A Hezbollah official said that three Lebanese Shiites have been killed in clashes in Syria, as the opposition accused the Shiite militant group of fighting alongside its regime allies.
Syria is witnessing a violent uprising against the regime of President Bashar al-Assad, which has so far killed more than 60,000 people since its outbreak in March 2011, according to figures released by the United Nations.
The FSA has grown from a rag-tag force of military defectors into a popular guerrilla insurgent movement buoyed by civilian recruits, and it now regroups thousands of fighters.
