BISHKEK, Kyrgyzstan - An opposition politician has seized the headquarters of a branch of Kyrgyzstan's security forces -- the first concrete sign that a violent uprising is now in charge of the Central Asian nation.

An Associated Press reporter saw opposition leader Keneshbek Duishebayev sitting in the office of the chief of Kyrgyzstan's successor agency to the Soviet KGB.

The reporter says Duishebayev was issuing orders on the phone to people he claimed were security agents.

The reporter also saw Duishebayev giving orders to a uniformed special forces commando.

Duishebayev told the AP that "we have created units to restore order" on the streets.

The mountainous former Soviet republic of Kyrgyzstan houses a U.S. military base that is a key supply centre in the fight against the Taliban in nearby Afghanistan.
