- More than 80 bodies are found in a mass grave in Deir Ezzor, an opposition group says
- They are among the 245 reported dead on Friday
- U.N.-Arab League envoy Lakhdar Brahimi arrives in Damascus
- Interference to broadcasts coming from Syria, a satellite provider says
A U.N.-Arab League envoy working for a cease-fire in Syria arrived in Damascus on Friday as warplanes pounded rebels and fighting engulfed the nation.
Lakhdar Brahimi "eventually" will be meeting President Bashar al-Assad during a trip expected to last several days, said Brahimi's spokesman, Ahmad Fawzi.
Brahimi wants to forge a cease-fire by Eid al-Adha, the Muslim holiday that arrives Thursday, and has been meeting with Middle East leaders to stoke momentum for stopping the violence.
"The hurdles are huge. We are appealing to the government to see the benefit of a period of calm where people can breathe. There's not going to be any joy in Eid -- exuberance amongst the Syrian people -- but at least they might bury less than a hundred people a day," Fawzi said, referring to the crushing daily death tolls.
Brahimi is appealing to the Syrian government to take the lead and make the first move.
"Of course, we appeal to the government to start first -- as the stronger party -- and then the opposition immediately after," Fawzi said. "Let's see what happens on the ground. There are no guarantees for anything in this conflict. They think they can shoot it out. We think they can't."
The United Nations and the League of Arab States, in a joint statement, called for support of Brahimi's cease-fire plan.
"This step needs to be sustained. It could create the space to allow a peaceful political process that realizes the legitimate aspirations of the Syrian people for democracy, equality and justice," the statement said.
More than 30,000 people have been killed in the 19-month conflict as scores have died daily in fighting. At least 245 people, including 20 children, were found dead across Syria on Friday, the opposition Local Coordination Committees said.
More than 80 of those killed were discovered in a mass grave "after they were field executed" in Deir Ezzor, the LCC said.
Ous al-Arbi, an activist in Deir Ezzor who visited the site, said women and children were among the dead. Some had been "slaughtered" and "burned," while others had their hands and other body parts "cut off by axes," he said.
The bodies were located near a street that is used to get out of the city, al-Arbi said. They were taken to an open space for identification.
"The doctors who were with us said the bodies appear to have been field executed first, then later some of them were burned. They also said some of the bodies are only a day old, and others a month old," al-Arbi said.
Meanwhile, the opposition Syrian Observatory for Human Rights said Syrian jets continued to shell towns and villages in Idlib province, in the north.
Warplanes targeted rebel fighters on the outskirts of a military camp. They also struck the key town of Maaret al-Numan and nearby villages, the observatory said.
Maaret al-Numan is strategically important because a highway from Damascus to Aleppo runs through the town. The Syrian army uses the highway to provide reinforcements in the north.
The observatory also reported injuries from heavy clashes in the Idlib town of Salqeen.
Fighting also flared in Aleppo. The Syrian army shelled the al-Sakhour neighborhood and fought to oust rebels there. Rebels shelled the government-controlled neighborhood of al-Midan with mortars and battled the troops.
The LCC also reported "intense" gunfire by security forces against demonstrators in Damascus.
The state-run Syrian Arab News Agency said government soldiers destroyed a water tank truck loaded with explosives driven by a "suicide terrorist" in Idlib. It also said it killed two "terrorists," one of whom was Lebanese.
As Syria endures tough Western sanctions over the government's actions, reports have emerged that international broadcasts are being jammed from inside the country.
"Deliberate and intermittent interference" to international broadcasters' signals "is coming from within Syria," satellite provider Eutelsat said Friday.
The BBC said that it and other broadcasters are "experiencing deliberate, intermittent interference to its transmissions to audiences in Europe and the Middle East."
"Deliberate interference such as the jamming of transmissions is a blatant violation of international regulations concerning the use of satellites and we strongly condemn any practice designed to disrupt audiences' free access to news and information," the BBC said.
