Thailand unrest: Behind Bangkok protest barricade

Thai demonstrators remain on the streets on the fourth day of what they say is an attempt to shutdown the capital, Bangkok.

The protesters want Prime Minister Yingluck Shinawatra to resign and cancel upcoming elections, but the government is vowing to push ahead with the 2 February vote.

As John Sudworth reports from Bangkok, there are fears that the window for a peaceful resolution is narrowing.
