ISLAMABAD, Pakistan — Pakistan's parliamentary elections will he held by mid-February, a month later than planned, the country's military ruler said Thursday, a day after President Bush urged him to hold the vote on time.

Opposition leader Benazir Bhutto denounced President Gen. Pervez Musharraf's pledge as insufficient and said he should step down as army chief within a week.

With anger over military rule spreading, the United States and domestic opponents are stepping up pressure on Musharraf to end the emergency rule imposed Saturday, shed his uniform and hold elections as planned in January.

Bush, who counts Musharraf as a key ally in the war on terror, telephoned him Wednesday to say he should step down as the military chief and hold the vote on schedule.
