PESHAWAR: Muttahida Majlis-e-Amal (MMA) leaders in NWFP have received threatening letters asking them to either publicly announce their support for Taliban and Al Qaeda or face the "consequences". Non-government organisations operating in areas such as Dera Ismail Khan, Tank, Bannu and Lakki Marwat have also been warned to stop their work. Sources said the letters accuse MMA leaders of "using Islam and the Taliban to win elections, but forgetting their promises after assuming power". Some MMA leaders had also received Rs 1,000-Rs 1,500 with the letters to "buy their coffins if they fail to announce their support for Taliban and Al Qaeda".
