Bangkok - a city under threat in a country where vast swathes of land are now underwater.<br/> This new aerial footage shows floodwaters inundating the outskirts of the Thai capital and threatening to swamp the city.<br/> About a third of Thailand's provinces are still affected while some industrialized provinces are completely submerged.<br/> So far, Bangkok has escaped the worst of the flooding but it's a desperate race against time.<br/> Here in Sai Mail district, just north of Bangkok, residents and officials are again working around the clock to build flood walls and prepare sandbags.<br/> Residents in seven districts northeast of the capital have been told to prepare for flooding as the volume of water running down from the centre grows.<br/> More than 300 people have been killed since July in the country's worst flooding in five decades.<br/> Sunita Rappai, Reuters
