ISLAMABAD, Pakistan — The Pakistani Taliban announced on Friday that they were extending a cease-fire until Thursday, after the release of a group of prisoners by the Pakistani government, to facilitate a fledgling peace process.

The Taliban had earlier announced a monthlong cease-fire on March 1 after talks broke down because of terrorist attacks by some militant groups who were opposed to holding talks with the government.

On Friday, Shahidullah Shahid, a spokesman for the Taliban, said the extension in the cease-fire was meant to let the government show its intent on carrying the peace talks forward.

“Tehreek-e-Taliban is once again showing seriousness and responsibility, and in order to wait for an answer from the government, is extending the cease-fire until April 10,” Mr. Shahid said, using the group’s formal name in a statement released to news outlets.
