Representatives of the Syrian government and Lebanese militant group Hezbollah have held face-to-face talks in Turkey to try ​to calm tensions between them, according to six sources briefed on the first known meeting between the longtime foes, Reuters reported. 

The Syrian officials and the Iran-aligned group met secretly at least once last month, the sources - who include two Syrian officials, a US official and a senior Lebanese security source close to Hezbollah - told Reuters.
