`Mary Kom` fame director Omung Kumar has shown his concern over heavy rainfall in Manipur and has urged people to come forward and help the victims.

Bijou Thaangjam, who played the role of Naobi in the 2014 biopic on boxer Mary Kom from Manipur, first wrote about the natural disaster in the state on his Facebook account.

`This is what (is) happening in #MANIPUR RIGHT NOW... The worst flood ever in about 200 years... 1000s of lives are at stake,` actor Bijou, from the north-eastern state and now based in Mumbai, posted on Sunday.

Kumar is also "sad to hear about the floods in Manipur".

"Please come forward to show your support for the people of Manipur. @BijouTH @Vanita_ok," tweeted the director.

At least 20 people were killed and a large number of houses destroyed in a landslide which devastated a village in Manipur's Chandel district, bordering Myanmar, on Saturday following heavy rain, officials said.

The death toll was likely to increase as many people were still reported missing.
