Ali Mussa Daqduq, an explosives expert and member of Hezbollah, has been captured in Iraq and is believed to have played a key role in the deaths of five Americans. According to Michael Ware at CNN, Dagdug pretended to be "deaf and mute" at first, but started talking once Americans discovered his identity
... they now believe he played a crucial role in the January 20 attack in Karbala.
Intelligence officials say Daqduq is one of Hezbollah's top special operations commanders, an expert in the use of roadside bombs. The Americans say he, along with the Iraqi militia commanders he worked with, has admitted working with Iran's elite Quds Force special operations unit.
Iran, which has close ties to the Shiite parties that control Iraqi Prime Minister Nuri al-Maliki's government, has repeatedly denied the allegations.
The U.S. military declined official comment on Daqduq's arrest, as did the Iraqi government. But documents and forensic evidence, seen by members of the Iraqi government and shown to CNN, support the claims.
Senior U.S. intelligence officials said Daqduq was captured in a raid aimed at seizing another Shiite militant leader suspected of involvement in the January 20 attack in Karbala.
U.S. sources and Iraqi militia sources have said the carefully planned operation was meant to take captives who could be traded for five Iranians held by U.S. troops since a January 10 raid in Irbil, in northern Iraq. But the Karbala attack went awry, resulting in the deaths of the five Americans.
Qais Khazali, a onetime spokesman for anti-American cleric Muqtada al-Sadr's Mehdi Army, was one of the men sought by American troops in connection with the attack. By the time of his March arrest, he had left the Mehdi Army and was leading one of the "special groups," according to U.S. intelligence.
In searching for Khazali, U.S. and allied troops found computer documents detailing the planning, training and conduct of the failed kidnapping. And they found Daqduq, whom intelligence officials said has admitted working on behalf of Iran.
