A top Iraqi security official on Wednesday said authorities had arrested a key al Qaeda suspect, a Tunisian, wanted in the bombing of the Shiite Golden Dome shrine last February in Samarra.
A spasm of sectarian killing and revenge attacks on Sunni and Shiite mosques after the bombing of the revered shrine in Samarra, 60 miles north of Baghdad, took the country to the brink of civil war.
Since then more than 20,000 familIes were displaced from their homes, hundreds of civilians were killed and dozens of mosques belonging to both Muslim sects were damaged or destroyed.
National Security Adviser Mouwafak al-Rubaie said the ringleader in the operation, an Iraqi he identified as Haitham Sabah Shaker Mohammed al-Badri, still was on the run.
Al-Rubaie identified the arrested man as Yousri Fakher Mohammed Ali, a Tunisian also known as Abu Qudama. He was seriously wounded in a clash with security forces north of Baghdad few days ago in which 15 other foreign fighters were killed, al-Rubaie said.
Abu Qudama and al-Badri were in a gang that included two other Iraqis and four Saudis who carried out the Feb. 22 attack, the security adviser said.

"It's going to take some time. We do not see an upward trend. We ... see a slight decrease but not of the degree we would like to see at this point," he said at a news conference in the heavily fortified Green Zone.An American soldier on a foot patrol south of Baghdad was killed Tuesday in a bombing, and a Marine died Tuesday in fighting in Anbar province west of the capital.

Casey Jr., the top military commander in Iraq, has outlined a strategy that could cut the number of combat troops in Iraq by nearly two-thirds by the end of next year.

The gang planted bombs in the 1,200-year-old Askariya mosque that exploded and obliterated its glistening golden dome, an addition completed in 1905.
While acknowledging al-Badri was still at large, al-Rubaie did not say if other members of the group had been captured.
Al-Rubaie said Abu Qudama, the captured Tunisian, was involved in the killing the of Al-Arabiya TV correspondent Atwar Bahjat, who was shot dead along with two of her colleagues hours after the shrine bombing.
Abu Qudama entered Iraq in November 2003 and was captured "few days ago" in Udaim, a village about 70 miles north of Baghdad, al-Rubaie said.
"Abu Qudama confessed that he killed hundreds of Iraqis" in different parts of the country al-Rubaie said but gave no further details.
"Iraqi forces and its intelligence have achieved major penetrations of al Qaeda and other terrorist groups," the national security adviser said.
