Belgian authorities say they are holding a man accused of a role in organizing the September assassination of Afghan commander Ahmad Shah Masood.
Officials at the prosecutor's office in Brussels say police arrested Amor ben Mohamed Sliti on charges of forgery and conspiracy last week in connection with the forged passports used by Masood's two killers.
Mr. Sliti, a Belgian citizen of Tunisian origin, had been detained in Iran among a group coming from Afghanistan before being transferred to the Netherlands and finally Belgium.
The assassins posed as Belgian journalists when they blew themselves up with Masood during a mock interview. The passports found on the bodies where stolen from the Belgian consulate in Strasbourg and the Belgian embassy in The Hague.
Masood led the Northern Alliance's fight against Afghanistan's ruling Taliban until he was murdered two days before the September 11th terrorist attacks in the United States.
