Bomb blast as Thai standoff continues

The stand-off between the government of PM Yingluck Shinawatra and thousands of protesters has taken a bloody turn with a bomb blast at an anti-government rally.

At least 28 people have been injured.

A prominent leader of the protest movement, Suthep Thaugsuban, was said to be just 30mt from the explosion.

Across Bangkok a host of government buildings have been shut down by mass demonstrations.

In all at least eight people have died since the protest campaign began in November.
