ISLAMABAD, Pakistan — Security forces overran a militant camp on the outskirts of Pakistani Kashmir's main city and seized an alleged mastermind of the Mumbai attacks, two officials said today.

Backed by a helicopter, the troops grabbed Zaki-ur-Rehman Lakhvi among at least 12 people taken Sunday in the raid on the riverbank camp run by the banned group Laskhar-e-Taiba in Pakistani Kashmir, the officials said. There was a brief gunfight in the camp near Muzaffarabad before the militants were subdued, the officials said.

The officials — one from the intelligence agencies and one from a government agency — spoke on condition of anonymity because they were not authorized to speak to the media.

Indian officials said the sole Mumbai attacker captured alive told them Lakhvi recruited him for the mission and that Lakhvi and another militant, Yusuf Muzammil, planned the operation, which left 171 people dead in India's commercial capital.

Your current casualties of hundreds will jack up to thousand casualties of dead and injured," said the statement, which was written in broken English and posted on a Web site Sunday that has previously carried militant messages.Violence in Afghanistan has spiked in the last two years, and 2008 has been the deadliest year for U.S. troops since the 2001 invasion to oust the Taliban for hosting al-Qaida chief Osama bin Laden.
