BAGHDAD (AP) — An Iraqi court has rejected a request to send a Hezbollah commander to the United States for trial, a decision that likely ends the Obama administration’s push to prosecute the Lebanese militant held in Iraq for the 2007 killings of five American soldiers.

The U.S. believes Ali Mussa Daqduq is a top threat to Americans in the Middle East, and had asked Baghdad to extradite him even before two Iraqi courts found him not guilty of masterminding the 2007 raid on an American military base in the holy Shiite city of Karbala.

But the July 30 decision by the Iraqi central criminal court, a copy of which was obtained by The Associated Press, ordered that Daqduq be freed immediately. It also makes it clear that Iraq believes the legal case against him is over.

“It is not possible to hand him over because the charges were dropped in the same case,” the three-judge panel ruled. “Therefore, the court decided to reject the request to hand over the Lebanese defendant Ali Mussa Daqduq to the U.S. judiciary authorities, and to release him immediately.”

The U.S. Embassy in Baghdad declined to comment Thursday and referred questions about the case to Washington.

At the Pentagon, Defense spokesman Lt. Col Todd Breasseale said Daqduq “should be held accountable for his crimes. Period.” Breasseale said the Pentagon “will continue to work closely with the Iraqi government to explore all legal options to pursue justice in this case.”

In an AP interview last month, the national security adviser to Vice President Joe Biden said the White House has asked Iraq’s highest appeals court to review and overturn its order to free Daqduq. It was not immediately clear Thursday whether that review was continuing.

Washington believes the Lebanese-born Daqduq worked with Iranian agents to train Shiite militias to target the U.S. military during the years of sectarian violence that gripped Iraq over the last decade. His case has illustrated the tricky aftermath of the long U.S. military campaign in Iraq that ended last year and has elements of both Iraqi and U.S. internal politics.Biden called Prime Minister Nouri al-Maliki on Thursday to discuss unspecified issues between the U.S. and Iraq, according to a statement released by the premier’s office. The statement did not mention Daqduq, but Biden has been following the case closely and has asked Iraq’s government to keep the militant locked up for as long as legally possible.
