Anti-government protesters in Thailand have crossed heavily fortified barriers to reach the gates of the Prime Minister's office.

There's been no resistance from police - after the government ordered officers to stand down to avoid any further violence, following three days of clashes.

Instead they stood and watched as crowds waved flags and blew whistles on the lawn outside government house.

Reporter Jonathan Samuels is in Bangkok, he has seen "protestors shaking hands with riot police and protestors are being invited inside the government compound, and inside the police headquarters."

At least three people have died and more than 230 people have been injured in street battles.
