International peace envoy Lakhdar Brahimi is to meet Friday in Damascus with members of the Syrian opposition who are tolerated by the regime of President Bashar al-Assad dpa reported
There was no official confirmation on reports that Brahimi will also meet al-Assad.
Brahimi, who arrived in the Syrian capital on Thursday and met Foreign Minister Walid al-Moallem, said the crisis was worsening.
Opposition activists said the envoy's presence in the country had not stopped the violence, as government forces pounded areas outside the Damascus suburb of Yalda to flush out rebels trying to regain control of some areas.
"Fifteen people were executed, most of them Palestinians ... who sought refuge in Yalda," activist Haytham al-Abdallah said.
State media reported that regime forces entered Yalda and liberated citizens from "terrorists" in the area.
"If Brahimi stands in his hotel room, he can see fighter jets flying overhead and helicopter gunships firing on Damascus suburbs," al-Abdallah told dpa from Damascus.
An estimated 190 people were killed across the country on Thursday, most of them in Aleppo, activists said.
