Pakistani politician Imran Kahn , a former cricket star and critic of US drone strikes, was briefly delayed and questioned by US immigration officials in Toronto before being allowed to board a flight to New York.
Khan told his followers on Twitter on Friday that he was detained and interrogated about his views on drones.
A State Department official confirmed Khan had been briefly detained, but said the Pakistani politician was later released to travel to the United States. "The issue was resolved and Khan is welcome in the United States," said the official.
The State Department provided no details about why Khan was detained, and officials with the US Customs and Border Patrol were not immediately available for comment.
Khan, who led a protest march to northern Pakistan earlier this month to protest US drone strikes , sent a message about the incident on Twitter on Friday, vowing to continue opposing the deadly attacks. "Nothing will change my stance," he said.
"I was taken off from plane and interrogated by US Immigration in Canada on my views on drones. My stance is known. Drone attacks must stop," Khan tweeted on Friday.
