A remarkable video has emerged from China showing a five-storey block of flats collapse into a flooded river.<br /><br />In the video, which was filmed in Chamdo Prefecture on July 8, the fast-flowing water appears to wash away the building's foundations and it topples over into the river.<br /><br />Luckily the residents were evacuated in advance and there were no casualties. <br /><br />The clip also shows a empty lorry falling into the river as part of the river bank subsided.
