The Syrian army kept up its bombardment of rebel neighbourhoods of the central city of Homs on Monday, a watchdog said, while violence killed at least seven people across the country.
Four civilians were killed in the eastern province of Deir Ezzor, said the Syrian Observatory for Human Rights, which added they died when the car they were travelling in was shelled.
One civilian was killed when regime forces shelled the rebel-held town of Rastan in Homs province, the Britain-based group said, adding a rebel was killed in the same province.
Another civilian was killed in Daraa, the Observatory said.
An activist in Homs told AFP via Skype that many civilians remained trapped in the shelling of the Jurat al-Shiah, Khalidiyeh and Old City neighbourhoods of Syria's third-largest city.
"Many neighbourhoods of Homs are still under siege, and it is really hard for us to get food or medicines in," said Khaled al-Tellawy.
"Field doctors are amputating the limbs of the injured because they have no equipment to treat them with, and they can't be smuggled out."
The besieged neighbourhoods of Homs are among a string of areas that have fallen into the effective control of rebel fighters, the Observatory said.
The International Committee of the Red Cross and the Syrian Arab Red Crescent attempted in late June but were unable to enter the hardest-hit districts of the city.
The Observatory revised its toll from Zamalka in Damascus province, where a blast killed 65 people during a mass funeral on June 30.
It initially reported at least 30 people had been killed in the town, situated 10 kilometres (six miles) east of the Syrian capital.
Also in the province of Damascus, regime forces shelled the Hammuriyeh fields near the village of Beit Sawa for a third day in a row, the Observatory said.
It also reported violent shelling and clashes between rebels and regime troops in several other areas of the country on Monday, including the southern province of Daraa, Aleppo in the north, and the central province of Hama.
More than 16,500 people have been killed in violence in Syria since the uprising against President Bashar al-Assad's rule erupted in March last year, according to the watchdog.
