Government aircraft bombarded Damascus and its Idlib and Homs suburbs Friday, the LCC said.
Homs government officials received a delegation from the International Committee for the Red Cross, which is attempting to negotiate with both warring parties over the safe delivery of aid to the hardest-hit areas of the historic center of town.
The Red Cross and the U.N. refugee agency have recently reported accomplishing inroads in aid delivery despite the dangers of battle and unexploded ordnance.
"We need to make sure both sides stop shooting before we move around," ICRC spokesman Alexis Heeb said from Geneva, Switzerland.
Government and opposition fighters clashed on the ground in Homs on Friday -- as well as in Damascus, Aleppo, Deir Ezzor and Daraa, according to opposition groups.
Fighting has killed 133 people so far Friday, the LCC said. Forty-two of those deaths occurred in Damascus and its suburbs.
Death tolls reported by Syria's opposition usually mount exponentially in the course of a day. At least 149 died Thursday, 121 on Wednesday and 163 on Tuesday, the LCC said.
CNN cannot independently confirm government or opposition reports out of Syria, as the government has restricted access by journalists.
