Tens of thousands of protesters in South Korea on Saturday held a mass rally against a raft of government policies that they believe have weakened democracy.
About 18,000 police have been deployed in the capital, Seoul, BBC reported.
Protesters oppose plans including changes to labour laws and greater controls over history textbooks.
A mass protest last month where about 60,000 people took part saw violent clashes between protesters and police and ended in a riot with water cannon being used to prevent marchers from getting to the presidential palace.
A 69-year-old went into a coma after being hit with the water cannon.
