Two car bombs went off separately at military checkpoints in Syria's central province of Homs on Sunday morning, killing at least two people and injuring many others, the pro-government Sham FM radio said.

The first car targeted an army checkpoint near a factory on the Homs-al-Masharfe road, killing one soldier and a civilian, the report said.

The second one targeted another checkpoint on the Homs-al- Jabirieh road near the Sheep Souk, leaving only property losses.

The twin blasts were also coupled with fighting between armed groups and soldiers at the Rayyan checkpoint in Homs, the report said, adding that many armed men were rounded up while others were killed.

Sunday's blasts are the latest in a series of explosions that have intensified over the past 24 hours in Syria.

A day earlier, at least 16 people were killed in separate explosions that rocked the capital Damascus and its countryside. The government in Syria accuses al-Qaida-linked Nusra Front of staging the blasts.
