Syrian warplanes carried out eight air strikes in the rebel-held al-Waer district of Homs on Thursday, a military media unit run by the government's ally Hezbollah reported.

The air strikes targeted militant groups and caused injuries, it said.

Although Homs, an early center of the uprising against President Bashar al-Assad, has been almost entirely held by the government since 2014, the al-Waer district in its western suburbs remains in rebel hands.

On Saturday militants from the jihadist Tahrir al-Sham rebel alliance staged suicide attacks in central Homs, killing dozens of people including the city's military security chief.

Fighting and air strikes in Syria have continued despite a ceasefire across the country that was brokered at the beginning of the year by Russia, Assad's main ally, and Turkey, a leading supporter of the rebels.

Government and opposition delegations are attending U.N.-sponsored peace talks in Geneva.

Assad is backed in the war by Russia's air force, Iran and Shi'ite militias including Hezbollah. Some of the rebel groups are also supported by the Gulf monarchies and the United States.
