West Bengal Chief Minister Mamata Banerjee on Wednesday said a BJP fact-finding panel's report on Birbhum killings, submitted to party president J P Nadda, will weaken and interfere with the CBI probe into the incident.

Eight people were burnt alive after assailants attacked a group of houses with petrol bombs in Bogtui village near Rampurhat on March 21, while one more succumbed to injuries a week later. The attack is being viewed as a revenge for the murder of local TMC leader Bhadu Sheikh hours earlier.
