New Delhi, Aug 11 (IANS): Gujarat Chief minister Narendra Modi Sunday said not allowing opposition leaders in trouble-torn Kishtwar in the Jammu region of Jammu and Kashmir is "undemocratic".

"Heard that Arun Jaitley and other opposition leaders are not allowed to go to Kishtwar. This is undemocratic," Modi tweeted.

He also said, "Stopping opposition leaders in this manner shows that the government does not want the truth about the Kishtwar violence to come out."

BJP leader Arun Jaitley was not allowed to proceed to Kishtwar after he landed at Jammu airport Sunday morning, and was requested to return.

Mehbooba Mufti, president of the People's Democratic Party (PDP) also said she was not allowed to enter Kishtwar.

The indefinite curfew in Kishtwar ever since riots broke out Friday has remained, without a break, for three days. Authorities also brought Jammu city and Rajouri town under curfew Saturday, in a bid to maintain law and order even as arson and tension spread to other parts of the state.
