North Korea sent 10 Scud missiles to Pakistan last month -- possibly in return for Islamabad's nuclear technology, AFP reports.

The 12 meter-long Scud B missiles, with the range of about 300 kilometers, "were loaded on a Pakistan-flagged cargo ship in North Korea's southwestern port of Nampo in mid-March, the wire service says. "The vessel was refueled at a Chinese port and entered Pakistani territory in late March."

In January, Seymour Hersh revealed in The New Yorker that North Korea and Pakistan had been collaborating for years on nuclear weapons programs.

Yesterday, North Korea conducted its third missile test since late Feburary, firing a short-range, anti-ship weapon into the Yellow Sea, off of North Koreaís western coast.
