At least 27 killed in attack on Afghan political rally: officials

An attack on a political rally in Kabul on Friday left at least 27 people killed, an official said, in what appeared to be the first violence to hit the capital since the US signed a withdrawal deal with the Taliban.

The Taliban immediately denied responsibility for the assault, which occurred at the commemoration ceremony for Abdul Ali Mazari -- a politician from the Hazara ethnic group, most of whom are Shiite.

An Islamic State group-claimed attack on the same ceremony last year saw a barrage of mortar fire kill at least 11 people.

Interior ministry spokesman Nasrat Rahimi said gunfire had erupted from a construction site near the ceremony in the city's west, which is largely Shiite.

At least 27 people had been killed so far, he added.

"Soon after the attack, police forces and police special forces units rushed to the scene," Rahimi told a local news station, noting that sporadic gunfire was ongoing.

Photos on social media showed at least two bodies, but there was no official word on a death toll.

"We left the ceremony following the gunfire, and a number of people were wounded, but I do not have any reports of martyred people for now," Hazara leader Mohammad Mohaqiq told Tolo News.

The ceremony was attended by many of the country's political elite, including Afghanistan's chief executive Abdullah Abdullah.

The interior ministry later confirmed to reporters that "all the high-ranking officials were safely evacuated from the scene".

The incident comes less than a week after the US and Taliban signed a deal that would pave the way for the complete withdrawal of foreign troops in 14 months.

However, fighting has continued to rage across the country, casting a pall over hopes that the agreement would lead to a reduction in violence.

IS, which follows the Sunni branch of Islam, first became active in Afghanistan in 2015 and for years held territory in the eastern province of Nangarhar.

It has claimed responsibility for a string of horrific bombings, including several in Kabul targeting the city's Shiite community.

In recent months the group has been hit by mounting setbacks after being hunted for years by US and Afghan forces along with multiple Taliban offensives targeting their fighters.

Still, IS remains in Afghanistan, notably in eastern Kunar province near the Pakistan border, which also neighbours Nangarhar, as well as in Kabul.
