Tehran, Iran-AP -- U.S. officials have accused Iran of harboring senior members of the al-Qaida terrorist network.
But Iran's top United Nations envoy says Tehran is holding al-Qaida members in custody, and they're being interrogated.
Javad Zarif told ABC's "This Week" that Iran probably has captured more al-Qaida members in the past 14 months than any other country.
Iran's foreign minister says his country has "no intention of sheltering al-Qaida." State-run Tehran Television quotes him as saying Iran was al-Qaida's enemy before the U.S.
Iranian officials believe the U-S accusations are meant to pressure Tehran to change some of its foreign policy positions, including its opposition to the Middle East peace process.
