Four civilians were killed in morning shelling of the rebel-held district of Baba Amr, in the central city of Homs, under bombardment for a 24th straight day, said the Syrian Observatory for Human Rights.
The Britian-based monitoring group said explosions shook the Homs neighbourhoods of Hamidiyeh, Bustan al-Diwan, and the city centre.
Two others were killed when a rocket fired by regime troops hit a car in which they travelled in the village of Talheya, in the northern province of Idlib, the Observatory said.
Eight civilians were wounded as troops shelled the town of Sarmeen, also in Idlib, according to the watchdog.
And in Rastan, in Homs province, 20 civilians were wounded in a huge blast that was heard across the city, it added.
Elsewhere, pro-regime gunmen known as Shabiha chased students staging a sit-in at the University of Aleppo's faculty of dentistry, the Observatory said, while in the central Hama province, military forces reportedly stormed the village of Khatab.
More than 7,600 people have been killed in violence across Syria since anti-regime protests erupted in March 2011, according to the Observatory.
