It is absolutely wrong that farmers are being prevented from holding peaceful demonstrations against the Centre's new farm laws and water cannons are being used on them, Delhi Chief Minister Arvind Kejriwal said on Thursday.

Haryana put up road barricades along its border with Punjab on Wednesday as farmers in the adjoining state massed with their tractor-trailers for their "Delhi Chalo" march to protest against the laws. Water cannons were used at least twice to disperse them and stop them from going to Delhi.
