A suicide bomber killed eight civilians in Kabul, Afghanistan, at a military convoy, located near the U.S. Embassy and NATO compound. Fox News reported:

U.S. Navy Capt. William K. Salvin, spokesman for the U.S. Forces-Afghanistan, said a coalition convoy was targeted by an improvised explosive device at about 8 a.m. local time. Three U.S. Army soldiers sustained non-life threatening wounds, and at least 25 civilians suffered injuries.

Gen. Jawid Kohistani, a former official at Afghanistan’s National Directorate Security (NDS) who closely monitors attacks, told Fox News that intelligence was received three days ago cautioning of an imminent attack against NATO forces, with more possible through the “fighting season” around diplomatic areas and guest houses.

An investigation of the attack, which is still in its early stages, indicates that the Haqqani network is behind the bombing. However, no group has claimed responsibility for the attack.

The attacker is said to have been targeting a convoy of NATO-helmed Resolute Support vehicles close to Massoud Square in the city center, igniting at a NDS checkpoint. At least eight have died and a further 25 wounded, officials said.

A military source told Fox News the bomber pretended to be a construction worker, with tools and a uniform, and when the convoy arrived he pressed the button.

More than an hour later, smoke could still be seen bellowing through the grey sky from the bomb site as scores of military aircraft hovered close by.

The dead have not yet been identified.
