KABUL, Afghanistan — At least five civilians have been killed after a bomb blast at the entrance of a mosque in the Afghan capital of Kabul on Sunday, a Taliban Interior Ministry spokesman said.
Qari Saeed Khosti confirmed the deaths. Initial reports indicate the explosion was caused by a roadside bomb. Three suspects have been arrested, Bilal Karimi, Taliban official spokesman said.
The bomb targeted the sprawling Eidgah Mosque in Kabul, where a memorial service was being held for the mother of Taliban spokesman Zabihullah Mujahid, who later tweeted the attack had claimed civilian lives.
Taliban fighters were not been harmed in the attack, Taliban spokesman Bilal Karimi told the Associated Press. Those killed in the attack were civilians outside the mosque gate. He did not provide a figure for the number killed and said an investigation was ongoing.
Emergency NGO, an Italian-funded hospital in Kabul, tweeted it had received four people wounded in the blast.
The area around the mosque was cordoned off by the Taliban, who maintained a heavy security presence.
No one immediately claimed responsibility for the attack. However, since the Taliban takeover of Afghanistan in mid-August, attacks by Islamic State group militants against them have increased. The rise has raised the possibility of a wider conflict between the two extremist groups.
IS maintains a strong presence in the eastern province of Nangarhar and considers the Taliban an enemy. IS has claimed several attacks against the Taliban, including several killings in the provincial capital of Jalalabad.
Attacks in Kabul have so far been rare, but in recent weeks, IS has shown signs it is expanding its footprint beyond the east and closer toward the capital.
On Friday, Taliban fighters raided an IS hideout just north of Kabul in Parwan province. The raid came after an IS roadside bomb wounded four Taliban fighters in the area.
