ISLAMABAD, Pakistan (AP) _ An opposition leader filed suit against the government today, alleging that it violated the civil rights of a Pakistani man extradited to the United States on charges of killing two CIA employees.

The leader of the Awami National Party charged that Mir Aimal Kansi's rights were ignored when he was whisked out of Pakistan last week without a hearing.

Kansi was extradited in a clandestine operation that has outraged many in this Islamic nation, where the United States is often thought to be involved in the day-to-day running of the country.

``The way in which Aimal Kansi was handed over to the U.S. agencies was against the constitution and self-respect of a country and amounted to depriving him of the country's legal protection and basic rights,'' said Aurangzeb Kansi, a lawyer and politician who is not related to Kansi.

Hamid Gul, a former general and head of Pakistan's secret service, also is filing a suit against the government.

Troubling questions remain over how and where Kansi was captured, and why he was flown to the United States without an extradition hearing, said S.M. Zaffer, chairman of the Human Rights Society of Pakistan.

``Our government has not made it very clear whether or not it followed regular procedures for his transfer to the United States,'' said Zaffer.

U.S. authorities earlier said Kansi was captured in an early morning raid at a hotel by a group of FBI agents and Afghan men.

Both U.S. and Pakistani authorities have refused to give details on Pakistan's involvement in Kansi's capture.

``If the reports are true, the procedure lacked legal ground. In fact it would amount to a sort of abduction,'' Zaffer said.
