Pakistan on Tuesday released 11 Iranians detained near the countries' border amid tensions over a deadly suicide attack in Iran that Teheran alleges has links to Pakistani intelligence officials, police said.
Authorities had first said the 11 were members of Iran's elite Revolutionary Guards, but then reversed course and identified them only as security officers. They were arrested Monday after shooting out the tires of a car carrying smugglers, Pakistan authorities said.
Police official Dadur Rehman said the paramilitary Frontier Corps released the Iranians after an investigation.
"I do not have any idea why they were released," Rehman added in a phone call with The Associated Press from the area where the Iranians were held. He said he had not been privy to the interrogation.
