Kabul bomb blast that targeted a mosque memorial service for Taliban leader's mother leaves at least 5 dead, says interior ministry

• A bomb blast in Kabul has left at least five civilians dead, a Taliban spokesman said.
• The explosion targeted a mosque where a memorial service for the Taliban spokesman's mother was taking place.
• The Islamic State on Monday claimed responsibility for the blast.

The Islamic State claimed responsibility on Monday for a bomb that targeted the entrance of a mosque in Kabul the day before and killed at least five civilians, Reuters reported.

The explosion took place outside the Eidgah Mosque, where a memorial service was being held for the mother of Taliban spokesman Zabihullah Mujahid, Al Jazeera reported.

"I heard the sound of an explosion near the Eid Gah Mosque followed by gun firing," Abdullah, a shopkeeper, told the AFP news agency.

Witnessed described seeing ambulances carrying wounded civilians to Kabul's Emergency Hospital, Al Jazeera reported. The hospital, Emergency NGO, said on Twitter that it was treating four patients. BBC reported that at least 20 people were injured by the blast.

Three suspects had been arrested in connection to the attack, Bilal Karimi, a Taliban spokesman, said, according to Associated Press, No Taliban fighters were harmed in the attack, he reportedly added.

Since the Taliban took control of Afghanistan in August, attacks by ISIS have risen.

The Afghanistan-based offshoot group ISIS-K, the Islamic State in Khorasan Province, has been responsible for attacks in Kabul, Jalalabad, and Mazar-i-Sharif in recent weeks, Al Jazeera reported.

In August, the group also claimed responsibility for a suicide bomb at Kabul airport that killed at least 169 Afghans and 13 US troops.

The Taliban and ISIS have long been sworn enemies, regularly clashing over ideological and economic disputes.

Zabihullah Mujahid previously told Al Jazeera the Taliban was actively "hunting down those who are sowing chaos" in the country.
