You will be given a definition of a task first, then some input of the task.
In this task, you're given two sentences. Indicate if the first sentence clearly entails the second sentence (i.e., one can conclude the 2nd sentence by reading the 1st one). Indicate your answer with '1' if the first sentence entails the second sentence, otherwise answer with '0'.

Sentence 1: ISLAMABAD, Pakistan The uneasy truce between the Pakistani government and Taliban militants in the Swat Valley appeared increasingly fragile on Monday as government forces attacked militants in a neighboring district for a second day, causing the main negotiator for the Taliban to break off talks. Maulana Sufi Muhammad, the pro-Taliban cleric who has been negotiating peace talks between the government and the Taliban in Swat, halted talks on Monday to protest the military operation in the Lower Dir district west of Swat, his spokesman said. Sentence 2: Maulana Sufi Muhammad is the chief of Tehrik Nifaz Shariat-e-Muhammadi.
