Thailand police and protesters clash in Bangkok

Thai police are confronting protesters at a site in central Bangkok, with several people injured and one police officer reported killed. Police are trying to retake official buildings and sites that have been blocked by demonstrators. Earlier on Tuesday, they arrested around 100 protesters outside a ministry building. Thailand has been embroiled in a political crisis since anti-government protests began in November. Demonstrators have occupied official sites over the past few months, calling on the government to step down. The government has announced that it wants to retake all the besieged buildings this week. The prime minister's office, Government House, has been a focal point for the demonstrators. Thousands gathered outside the building on Monday, cementing the gates shut in a bid to stop officials returning to work, according to BBC.
