Two contractors working for the U.S.-led military coalition in Afghanistan were killed in a suicide car bomb attack in Kabul on Monday, the Los Angeles Times reported.
According to an official at Pul-e-Charkhi prison -- near the location of the attack -- the two victims were American security advisors. Though the North Atlantic Treaty Organization (NATO) issued a statement on the deaths, they did not detail the nationalities of the contractors.
A tweet was also uploaded to the ISAF Joint Command account.
"Two International Security Assistance Force contracted-civilians died as the result of a VBIED attack in eastern #Afghanistan today," the tweet read.
Zubair Sediqqi, a spokesman for the Hezb-i-Islami militant group led by Gulbuddin Hekmatyar, claimed responsibility for the attack.
Around 2:30 p.m. local time, a Toyota Corolla full of explosives crashed into the Kabul convoy, said police spokesman Hashmat Stanikzai. Three Afghan officials were also injured in the blast.
Immediately after the attack, medical personnel, U.S. military officials, and Afghan security forces arrived at the scene. According to the LA Times, the area was covered in car parts and windows of nearby shops were shattered.
Stanikzai added that people working for the Corrections System Support Program -- a State Department-funded program that trains prison officials and helps rehabilitate former insurgents -- were at the convoy at the time of the assault.
