Few signs of foreign intervention in Syria

>> been another awful day in syria . the continuing government crackdown on protesters who want president assad out. richard is tracking it from benghazi. the problem today was syrians firing on their own people?

>> reporter: it was, and that has been the problem from the start. the syrian government has denied entry visas to foreign journalists. it doesn't want to world to see what it is doing, which is a systematic city by city sweep against protesters. overnight, syria deployed tanks in this city. witnesses say cdozens of tanks have set up checkpoints and shelled the city earlier. even as funerals were held for protesters held in the seven-week crackdown. human rights protesters say they documented over 700 killings since the unrest began. more than 10,000 have been arrested, and there are no signs of foreign intervention coming or if the syrian government has any intention of stopping. syrian president bashar assad said he's fighting an arm ed infection outside of the country. the european unit has imposed an arms embargo on syria . but outside pressure isn't working. the assad regime believes it's in a fight for its survival. human rights groups in syria say at least 18 people were killed today alone.

>> richard , before you go, about libya, where you are, a lot of talk about gadhafi. nato says they're not trying to kill him, but they killed his son, kit his house in the last raid. it's been a long time since we have seen moammar gadhafi alive.

>> reporter: well, we have seen him, according to libyan state television tonight, the state television broadcast pictures without any date, showing gadhafi, apparently greeting tribal elders. he was wearing sunglasses. he expressed no emotion as he greeted the elders who seemed very unenthusiastic about the meeting. he was inside, in a building that appears to be a luxury hotel in tripoli.

>> richard , thanks for all of tt.
