Gaddafi protests outside Libyan embassy in London

Around 200 people have held a protest outside the Libyan embassy in London calling for Col Muammar Gaddafi to leave office.

The protesters are angry after details emerged of huge casualty figures in the Libyan city of Benghazi, where troops have launched a brutal crackdown on protesters.

More than 200 people are known to have died, doctors say, with 900 injured.

One of the the organisers, Lucinda Levalle from the British Libyan Solidarity Campaign, told the BBC's Helen Fawkes that despite closer trading links between the UK and Libya, nothing had changed politically.
