Human rights groups in Syria say a city-by-city crackdown on anti-government protesters is spreading, with troops rounding up
opposition leaders.

They say more than 770 people have been killed since the uprising began in March.

Foreign reporters are banned from the country.

But the associate editor of The Times of London, Martin Fletcher, recently managed to get in on a tourist visa.

CNN's Randi Kaye spoke with him earlier today.
