A bombing at a mosque in the Afghan capital of Kabul during evening prayers on Wednesday killed at least 20 people, including a prominent cleric, an eyewitness and police said.
There was no immediate claim of responsibility for the attack.
According to the eyewitness, the explosion was carried out by a suicide bomber.
He added that more than 30 other people were wounded. The Italian Emergency hospital in Kabul said that at least 27 wounded civilians, including five children, were brought there from the site of the bomb blast.
Khalid Zadran, the Taliban-appointed spokesman for the Kabul police chief, confirmed an explosion inside a mosque in northern Kabul but did not provide a casualty toll or a breakdown of the dead and wounded.

Taliban spokesman Zabihullah Mujahid also condemned the explosion and vowed that the “perpetrators of such crimes will soon be brought to justice and will be punished." A U.S.-led invasion toppled the previous Taliban government, which had hosted al-Qaida leader Osama bin Laden in Afghanistan, following the Sept. 11, 2001 terrorist attacks in the United States.
Since regaining power, the former insurgents have faced a crippling economic crisis as the international community, which does not recognize the Taliban government, froze funding to the country.
Separately, the Taliban confirmed on Wednesday that they had captured and killed Mehdi Mujahid in western Herat province as he was trying to cross the border into Iran.
Mujahid was a former Taliban commander in the district of Balkhab in northern Sar-e-Pul province, and the only member of the minority Shiite Hazara community among the Taliban ranks.
Mujahid had turned against the Taliban over the past year, after opposing decisions made by Taliban leaders in Kabul.
