On its website, the party said, "The Guardian newspaper questions the credibility of Modi's development model and indicts Modi for his role in the riots in Gujarat in 2002", referring to an opinion piece in the April 7 edition.
It concludes by saying that "Modi is much more than a divisive figure". He is a man who "bears a responsibility for some of the worst religious violence ever seen in independent India," the party said, posing the question to people-- "The world doesn't trust Modi, do you ?"
The latest attack has come close on the heels of Congress targeting Modi by heaping praise on former Prime Minister and BJP leader A B Vajpayee.
The Congress had even gone to the extent of asserting that no leader in the BJP can match the stature of Vajpayee, while questioning Modi's record during 2002 riots.

"How can a person who failed in his 'Rajdharma' as a Chief Minister ever ensure a peaceful and prosperous future for the people of India.
"Vajpayee was clear what was the reason for the defeat: Gujarat CM Narendra Modi's failure to control the communal pogrom in his state in 2002... Who failed to protect his citizens, who discriminated between people on the basis of religion, who made a mockery of people's suffering, ever make a good PM," the website had said.
BJP had hit back saying Congress was showing its "utter desperation" by heaping praise on Vajpayee to attack Modi as it has been one of the worst critics of the former Prime Minister and termed the ruling party's public appreciation as "not bona-fide".
