During morning rush hour two suicide bombers attacked a NATO compound in Kabul, Afghanistan on Wednesday, killing two guards and wounding at least five.
"The bomber killed himself in front of the compound. Two people were killed and two more were wounded, all Afghan guards," said Interior Ministry spokesman Najib Danesh, according to Reuters.
The Washington Post reported that five civilians had also been wounded.
One detonated his vest. The other was shot dead by Afghan security forces.
"The attacker wanted to get into a building under construction, and this is when he was shot by security forces,'' police chief Salangi Kabul told the BBC.
Taliban spokesman Zabihullah Mujahid told Reuters his terrorist group was responsible for the attack.
No one is sure who or what the intended target was.
“It is still confusing what was the target. There are so many possible ones right here,” one investigator told the Post, who reported a damaged SUV "belonged to a senior Afghan army general," who was reportedly not hurt.
Meanwhile, near the US embassy in Kabul, a suicide bomber killed three Afghan security guards and injured two civilians, according to The New York Times.
One salient detail in their report: The bombers wore "private security uniforms."
As in the bombing of the NATO-run compound, a bomber wore a friendly uniform, this time an Afghan National Army uniform, according to the Washington Post.
It's not the first time terrorists have gained access to secure areas disguised as Afghan police or security forces.
