Interim Afghan leader Hamid Karzai says the killing of the aviation and tourism minister was carried out by a conspiracy that included top-level officials in the government.

Karzai told a news conference Friday night in Kabul that Abdul Rahman wasn't killed in a spontaneous attack by a mob of angry pilgrims.

"He was killed by people who planned it," Karzai said. "We are asking the Saudis to arrest them and bring them back...We will try them. We will put them behind bars."

Information Minister Abdul Rahim Makhdoom released the names of five men wanted in connection with the attack. Two of them are generals, while others belong to the intelligence service and the justice ministry.

Three are thought to be on flights to Saudi Arabia along with pilgrims heading for Mecca.

Witnesses at the airport said Muslim pilgrims were enraged because of delayed flights on Thursday night.

Hundreds of people were waiting at Kabul airport when they blocked Abdul Rahman's plane and stormed inside. Airport officials and witnesses say Rahman was attacked by the mob, who then threw his body onto the tarmac.

Afghan guards responsible for the minister's safety couldn't hold back the crowd.

Rahman, 49, was a trained medical doctor who friends and family say was committed to rebuilding the country.

Cabinet members of the country's interim government held emergency meetings late into the night after the incident, which preceded the arrival of British Foreign Secretary Jack Straw.

Security was intense when Straw's plane landed. He offered his sympathy to Karzai.

The violence continued Friday when a large crowd tried to push their way into a Kabul soccer stadium to watch a goodwill match between an Afghan team and a squad of international security force members.

The mob fought with Afghan police and international soldiers who were forced to fire warning shots into the air.

The incidents have some in the Afghan and international communities concerned about the capability of Afghan security forces.
