Haryana police has registered cases against protesting farmers in Ambala.
Cases lodged after farmers allegedly blocked Chief Minister Manohar Lal Khattar's convoy.
The Haryana CM was going to Ambala to campaign for BJP candidates in municipal corporation polls.
"A group of farmers blocked the convoy of Haryana CM.
We have registered cases against 13 farmers under various sections of IPC," said Madan Lal, DSP, Ambala.
Hundreds of farmers have been protesting on the outskirts of Delhi since November 26.
Farmers are protesting at different Delhi borders against Centre's newly enacted farm laws.
Govt has held many rounds of talks with farmers' unions offering changes to the farm laws.
Farmers are firm with their demand that Centre should repeal the three new laws.
