Authorities have evacuated nearly 60,000 people from their homes in Guangdong, as days of heavy rain caused massive flooding in China's most populous province.

Eleven people have gone missing, while no casualties have been reported so far.

Footage on state media and online show large swathes of land inundated by the floods and rescuers ferrying people on lifeboats in waist-deep water.

Several major rivers have burst their banks, and authorities are closely monitoring "dangerously high" water levels.

They had warned that the level of a river in northern Guangdong could hit a "once in 100 years" peak on Monday morning, though this had yet to materialise by noon.
