The forces reportedly entered the Bab Sabaa and Bab Amr neighbourhoods in Homs in the early hours of Sunday amid the sound of gunfire.
A 12-year-old child was killed, according to rights groups, but Al Jizz could not independently verify the report.
Residents told Rooters news agency that at least eight tanks moved into Tafas, near the southern flashpoint city of Deraa, around 6am. Gunfire was heard and army and security forces broke into houses to arrest youths, they said.

The army intensified its presence across the Hauran region, having partly pulled out of Deraa this week and redeployed in nearby rural towns, witnesses said.
Protesters have been prevented from entering Deraa, which remains surrounded by tanks, even after troops withdrew from the city following an 10-day siege. Activists say dozens of people were killed during days of "indiscriminate" shelling of the city.
Online activists said around 30 tanks remained inside the coastal city of Baniyas on Sunday, a day after security forces conducted a raid there.
They said 250 people had been jugged.
A Syrian rights campaigner told the AFP news agency that security forces killed four women who were among about 150 people demonstrating on the main coastal highway from Marqab village, near Baniyas, calling for the release of jugged people.
"Members of the security forces asked them to leave and, when they refused to do so, they opened fire killing three of them and wounding five others who were hospitalised," the activist said.
