Kabul, Afghanistan (CNN) -- A suicide attack in Afghanistan's Kandahar province killed at least 17 people and wounded 23 others on Friday, officials said.
The explosion took place in the southeastern town of Spin Boldak, a hotbed of Taliban militants.
The suicide attacker detonated himself in a public bath where the border police commander was bathing, said the spokesman for the governor of Kandahar province.
Two border police officers and 21 civilians were wounded in the attack.
NATO's International Security Assistance Force, Afghan President Hamid Karzai, Kandahar's provincial governor and the United States condemned the attack.
"This callous terrorist act was aimed at men gathered to wash before Friday prayer," the U.S. Embassy in Kabul said.
Elsewhere, three coalition service members died after bombings Friday. Two died in an incident in the east and another was killed in the south. The precise locations and the nationalities of the troops were not available.
