An anti-government 'red shirt' protester carries tyres out of the Chidlom sky train station, as a skytrain security official (L) and 'red shirt' security guard (R) watch, in the main shopping district in Bangkok April 27, 2010. A group of 'red shirts' had earlier stacked tyres on the platform of the rail station by their protest site, apparently worried troops would try to use the elevated system to attack them from above. As a result, operating company BTS closed down the network for three hours, adding to the congestion on Bangkok's famously crowded roads. (Reuters)
