Syrian officials have denied reports that President Bashar al-Assad's motorcade came under attack Thursday as he traveled to a mosque in Damascus.
The rebel brigade Tahrir al-Sham said it fired artillery shells in the direction of the motorcade, and that some hit their target.
Information Minister Omran al-Zoubi called reports of an attack completely false.
State television broadcast video of Mr. Assad praying at a mosque in the capital Thursday, as part of the Eid al-Fitr holiday marking the end of Ramadan.
The Britain-based Syrian Observatory for Human Rights said mortar rounds hit the nearby Malki district of central Damascus, but did not confirm an attack on Mr. Assad's motorcade.
It is difficult to independently confirm events in Syria because of restrictions on international media.
