A bomb attack on a military bus in central Damascus has killed 14 people, Syrian state media say.
Two explosive devices attached to the vehicle blew up as it passed under Jisr al-Rais bridge during the morning rush hour, Sana news agency reported.
Although Syria has been embroiled in civil war for a decade, such attacks in the capital are increasingly rare.
Soon afterwards, army shellfire also reportedly killed at least 10 people in the opposition-held north-west.
The region is the last stronghold of the rebel and jihadist groups that have been trying to overthrow President Bashar al-Assad since 2011.
The war has left at least 350,000 people dead, and caused half the population to flee their homes, including almost six million refugees abroad.
Wednesday’s bombing in Damascus was reportedly the deadliest in the city since March 2017, when 31 people were killed in a suicide attack at the main court complex that was claimed by the jihadist group Islamic State (IS).
“I was sleeping when I heard a strong explosion. I woke up and saw a bus on fire, which came to a halt after hitting the sidewalk,” Abu Ahmed, a fruitseller at a market near the bridge, told AFP news agency. “I later heard the sound of a second explosion, but this one was not as strong as the first one.”
Video from the scene showed the charred remains of the bus, with smoke billowing from its broken windows as firefighters put out the flames.
Sana said military engineers defused a third explosive device that had fallen from the vehicle.

Damascus police commander Maj Gen Hussein Jumaa called the attack a “cowardly act”.
No group has yet said it was behind the bombing, but suspicion will fall on IS, which has attacked military vehicles in the east of the country this year.
Four children and a woman were among the 10 people killed in the town of Ariha, in the north-western province of Idlib, according to the Syria Civil Defence, whose rescue workers are widely known as the White Helmets.
Another 20 people were wounded, some of them critically, when shells struck residential areas and a busy market at a time when children were heading to school, the organisation said, blaming pro-government forces.
“We woke up to the bombardment. The children were terrified and were screaming,” Bilal Trissi, a father-of-two who lives in Ariha, told AFP. “We didn’t know what to do or where to go and we didn’t see anything because of all the dust around us.”
North-western Syria has seen sporadic violence since a ceasefire brokered in March 2020 by Turkey and Russia ended a government offensive.
Turkey, which backs the opposition, and Russia, a key ally of Mr Assad, have deployed troops to the region in an attempt to prevent a major escalation.
