(AP) KABUL, Afghanistan - A suicide bomber blew himself up Saturday in a wedding hall in northern Afghanistan, killing at least 23 people including a prominent warlord-turned-politician and three Afghan security force officials, in an attack that deals a setback to efforts to unify the nation's ethnic factions, Afghan officials said.
Ahmad Khan Samangani, an ethnic Uzbek and anti-Soviet guerrilla leader in the 1980s who later became a member of parliament, was welcoming guests to his daughter's wedding when the explosion occurred in Aybak, the capital of Samangan province.
President Hamid Karzai said 23 people were killed and about 60, including government officials, were wounded in the attack, which he condemned and said was "carried out by the enemies of Afghanistan." He ordered a team from Kabul to fly to the northern province to investigate the bombing.
No one has yet claimed responsibility for the blast. But in announcing their spring offensive on May 2, the Taliban said they would continue to target those who back the Karzai government and the U.S.-led international military coalition.
Karzai needs the minority groups loosely known as the Northern Alliance to back his efforts to reconcile with the Taliban. But minorities already worry that Karzai, a Pashtun, will make too many concessions to their Taliban enemies to achieve a peace deal to end the war. Whatever support for peace talks that Karzai has won from minority groups is likely to erode if militants continue to pick off their leaders one by one.
It was the most recent in a month-long string of deadly attacks around the country.
On June 22, heavily-armed Taliban fighters attacked a lakeside hotel north of Kabul and killed 18 people during a 12-hour standoff with security forces. Two days earlier, a suicide bomber killed 21 people, including three U.S. soldiers, at a checkpoint in a crowded market in the eastern city of Khost.
The violence threatens to undermine international hopes of an orderly handover to Afghan forces by the end of 2014.
Separately, NATO said one of its service members was killed Saturday in an insurgent attack in eastern Afghanistan. It did not provide further details or release the nationality of the service member. The death brings the death toll among foreign troops to 19 so far this month and a total of 234 so far this year. And in western Afghanistan, Abdul Salam Rahimi, the mayor of Shindand district in Herat province, was assassinated Friday evening by two gunmen on a motorbike, authorities said. A civilian, who was injured in the shooting, later died at a hospital.
Mohammad Nawab Sherzai, criminal investigations director in Aybak who was helping provide security for the wedding, said most of the local guests had already gathered on the second and third floors of the three-story wedding hall when the morning explosion occurred. Samangani and other relatives and elders had moved to the first floor to welcome additional guests arriving from Mazar-i-Sharif, the capital of neighboring Balkh province.
"Suddenly, the attacker, who was among the guests from Mazar-i-Sharif, got very close to Samangani. He detonated his suicide vest," Sherzai said. "It was a big explosion. There were bloody bodies all around the first floor. The explosion was so strong. There were people even on the third floor who were wounded."
"Everybody was running in different directions. For about 10 minutes, nobody knew what was happening," he said. "There was dark smoke all around. After about 10 minutes, the people were able to see the bodies and start helping with the wounded."
The three Afghan security force officials killed were Afghan National Police Gen. Sayed Ahmad Sameh, the commander for the western region and a relative of Samangani; Gen. Mohammad Khan, the intelligence chief in the province; and Mohammadullah, an Afghan National Army division commander who uses only one name, which is common in Afghanistan.
The wounded included a lawmaker from Balkh province and a former governor of Sar-e-Pul province.
After the blast, shattered glass, blood and other debris and covered the site and the injured were helped from the scene. Afghan Army helicopters and ambulances ferried some of the wounded from rudimentary medical facilities in Aybak to Mazar-i-Sharif, which has larger hospitals. Dead bodies were piled into the back of Afghan security force vehicles and taken from the wedding hall, which has a facade of pillars painted a festive light green and pink. The wedding never occurred.
