14 Nepalese security guards have been killed after a Taliban suicide bomber attacked on their minibus on Monday (June 20, 2016) in Kabul, Afghanistan as told by the Interior Ministry and an Afghan security official to Associated Press (AP).

The Nepalese were on their way to the Canadian Embassy where they work as guards, according to another Nepalese guard who was wounded in the attack.

An Interior Ministry statement confirmed that all 14 killed were Nepalese citizens, describing the attack as the work of a “terrorist suicide bomber.” It said the explosion also wounded nine people, five Nepalese employees and four Afghan civilians.

It was the latest attack by the Taliban, who have stepped up assaults, including in the Afghan capital, as part of their summer offensive. The insurgents frequently target government employees and Afghan security forces across the country.

Prime Minister KP Sharma Oli has condemned the incident.

PM Oli tweeted,“I have been stunned by the Kabul suicide bombing in which 14 innocent Nepali migrant workers were killed.”

Meanwhile, he has also expressed heart-felt condolence to the families of victims and wished speedy recovery for those injured in the unspeakable incident.
