German authorities have released a Lebanese man arrested in connection with an alleged plot against Iraqi interim Prime Minister Iyad Allawi.
But prosecutors have issued arrest orders against three others accused of planning to attack Mr. Allawi during his visit to Germany last week.
Prosecutors identified the three as suspected members of the Islamic militant group Ansar al-Islam, which U.S. authorities have linked to al-Qaida.
Authorities detained the suspects in several German cities just hours before a meeting Friday between Mr. Allawi and German Chancellor Gerhard Schroeder in Berlin.
The Iraqi leader changed his travel plans after the alleged plot was uncovered.
