The United Nations Assistance Mission in Afghanistan (UNAMA) condemned an attack on a Kabul sports centre on Wednesday, which killed at least 22 people, including first-responders, sportsmen, and two journalists who were covering the initial bombing for a local news agency.

Around 75 others were wounded, according to media reports.

The first of two blasts occurred when a suicide bomber detonated himself inside a gym at a wrestling event. A car bomb was triggered soon after, as first responders attended the scene.

“This latest cynical act of terror targeting ordinary citizens of Kabul, along with first responders and journalists, is deeply shocking,” Tadamichi Yamamoto, the UN Special Representative for Afghanistan, said in a statement. The sports centre is located in Kabul’s Dashti-i-Barchi suburb, which is predominantly a Shi’a Muslim neighbourhood.

UNAMA said it has documented a pattern of attacks deliberately carried out against this minority community in recent years, the latest of which occurred on 15 August at an education centre.

As the Shi’a community prepares in coming days to commemorate Ashura“ at which time millions of Shia Muslims globally mark the martyrdom of the Prophet Mohammed’s (PBUH) grandson at the Battle of Karbala, “immediate and long-term security measures must be commensurate with the continued risks this community is facing”, UNAMA said in a statement released on Thursday.

The UN Mission demanded that “the orchestrators of this campaign of systematic attacks against the Shi’a Muslim religious minority face justice for their crimes.”

It also expressed its deep concern over the heavy price paid by Afghan media during the years-long civil conflict, with the killing of journalists in Afghanistan being among the highest in the world, and extended its deep condolences to families who had lost loved ones and wished the injured a quick recovery.

“We join Afghans in expressing our revulsion at such a callous attack,” Yamamoto added.

According to news reports, while the Taliban denied responsibility, the attack bore the hallmarks of the terrorist group ISIL/Da’esh, which has carried out a wave of bombings against minority Shias in recent years.

In July, UNAMA released figures highlighting the tragic toll the conflict has had on civilians, revealing that the first half of 2018 was the deadliest for Afghans since the Mission began documenting civilian casualties in 2009.
