A spate of sectarian kidnappings in Lebanon in the past week has left many Syrians living in the country in fear, CBC's Derek Stoffel reported.
Last week, more then 20 people, some described as a members of the Syrian rebel forces, were kidnapped in Lebanon by members of a powerful Shia clan.
"The situation in Beirut has become more dangerous than we ever imagined," said Khalil Hassan, a long-time Syrian anti-government activist.
Beirut has been home to all kinds of people opposed to the Syrian regime for years now, but Hassan said that's changing.
