BEIRUT (AP) -- Syrian troops pressed an offensive near Lebanon on Saturday, heavily bombarding a rebel-held town and forcing many residents to flee to safety across the border, activists said.
The violence came as an activist group said the death toll in the three-year Syrian conflict has reached 140,000. The Britain-based Syrian Observatory for Human Rights said the figure includes civilians, rebels, members of the military, pro-government militiamen and foreign fighters.
The group based its count on information from a network of informants on the ground.
The group said violence had escalated of late, with more than 3,400 people killed so far this month even as the government and opposition hold peace talks in Geneva. Since Jan. 22 when talks began, 5,792 people have been killed.
U.N.-Arab League mediator Lakhdar Brahimi ended a mere half hour of direct talks between the Syrian government and opposition Saturday with the situation still at an impasse and the future of negotiations in in doubt. No date was set for a third session.
The U.N.'s human rights office said in January it had stopped updating its own tally of the Syrian dead because it can no longer verify the sources of information that led to its last count of at least 100,000 in late July.
As the Geneva talks ended, two senior opposition figures said the government has put the top members of the Syrian National Coalition, the main opposition group in exile, on a terrorist list and ordered confiscation of their assets. They said the list includes the coalition's president and vice presidents as well as others including members of the political committee.
The Coalition's Haitham al-Maleh and Ahmed Ramadan told The Associated Press Saturday that they were among the opposition figures whose assets were ordered seized by authorities in Damascus. They said the list was issued by Syria's Justice Ministry although there was no confirmation from Damascus.
Top government negotiator Bashar Jaafari told a reporter during a news conference in Geneva Saturday when asked about the list that "the decision that you are talking about was issued two months before the Geneva talks. For your information this has nothing to do with the meetings in Geneva." He did not elaborate.
Also Saturday, the Coalition said its leader entered rebel-held areas in the northwestern province of Idlib a day earlier. Moderate rebels in the area are fighting government forces on one front and members of the al-Qaida-breakaway group, the Islamic State of Iraq and the Levant.
"I have come here to say we are with you. We are connected with this land and will not compromise on the values of this Revolution. We will get rid of this corrupt and criminal family who has been ruling this country for decades," a coalition statement quoted Ahmad al-Jarba as saying, referring to the Assad dynasty that has ruled Syria since 1970.
It was not the first visit by al-Jarba to rebel-held areas, but is significant because it came as the Geneva peace talks flounder. Al-Jarba spends much of his time in Turkey.
The Observatory said the government shelling concentrated on the town of Yabroud as well as nearby villages of Sihil and Falita. It had no immediate word on casualties.
State-run Syrian TV said troops killed several members of al-Qaida-linked Jabhat al-Nusra in the hamlet of Rima Farms on the edge of Yabroud. It added that large amounts of ammunition were also destroyed by government forces in the area.
Amer al-Qalamouni, an activist in the area, told The Associated Press via Skype that poor weather had grounded government warplanes. "Most of today's shelling is either artillery, mortar or with tanks," al-Qalamouni said.
He said government troops were backed by members of Lebanon's militant Hezbollah group, which openly joined President Bashar Assad's forces in the battle against opposition forces last year. He said the fighting was concentrated in areas near Yabroud such as Rima Farms and Qastal.
The army along with Hezbollah fighters has been on a crushing offensive in the Qalamoun region since early December, trying to sever a main thoroughfare for rebels from Lebanon. Yabroud, which has a large Christian population, is the last major town in the region to still be held by rebels.
Kasem Alzein, a Syrian doctor who lives in the Lebanese border town of Arsal, said six wounded people were brought from Syria for treatment early Saturday. A long line of cars and trucks carrying people are fleeing toward Lebanon, he added.
Alzein said about 1,000 families and some 35 wounded people have arrived in Arsal over the past days. The town's population has almost doubled over the past two years because of the flow of Syrian refugees.
