At least six people were killed and 12 others were wounded on March 27 when a suicide bomber blew himself up near the Foreign Ministry in the Afghan capital, Kabul.
Khalid Zadran, a spokesman for the Taliban's security command in Kabul, said security forces spotted the bomber and shot at him but could not prevent him from reaching a checkpoint in Malik Asghar Square, where he detonated his explosive vest.
A Kabul hospital run by Emergency, an Italian NGO, said on Twitter that it had admitted 12 wounded patients, including a child, and two people were dead on arrival.
No group has claimed responsibility for the attack so far, but after returning to power in 2021, the Taliban has been targeted by Islamic State-Khorasan (IS-K), an offshoot of the Islamic State militant group that has emerged as the Taliban's main rival in the war-wracked country.
IS-K has staged several attacks in Afghanistan recently.
On January 11, an IS-K suicide bomber killed at least 10 people when he blew himself up near the Foreign Ministry, not far from the site of the March 27 attack.
IS-K also claimed a bombing near a checkpoint at the Kabul military airport on January 1 that killed up to 20 people and an attack in December on a Kabul hotel frequented by businesspeople. At least five Chinese nationals were wounded in the December attack on the hotel.
In September, two Russian Embassy employees were killed in an IS-K suicide attack outside Moscow's mission in Kabul.
The Taliban has responded to the attacks by stepping up raids on suspected IS-K hideouts.
Last month, Taliban security forces said they had killed two senior IS-K members -- Qari Fateh, the regional IS-K intelligence and operations chief, and another senior leader, Ijaz Amin Ahingar -- in two separate raids in Kabul.
