* Eight civilians killed, 25 wounded, three US troops wounded
* Suicide bomber targeted Nato coalition vehicles
* Several civilian cars badly damaged or destroyed - witnesses


Islamic State claimed responsibility for a suicide bombing in the Afghan capital, Kabul, on Wednesday that killed eight civilians in an attack on a convoy of Nato armoured personnel vehicles.
The blast hit the Nato coalition convoy during the morning rush hour in one of the busiest areas of Kabul.
Public health officials in the capital said eight civilians were killed and at least 25 wounded, with a number of civilian vehicles that were near the convoy destroyed or badly damaged.
A Resolute Support Spokesman, US Navy Captain Bill Salvin, said three US service members were wounded in the attack.
The armoured personnel carriers, which are designed to withstand large blasts, were able to return to a coalition base under their own power, he said.
The attack follows a threat by the Taliban to target foreign forces in the spring offensive that it launched last week.
Witnesses said traces of blood and clothing could be seen on the ground at the blast site. Kabul television stations earlier reported that at least three people had been killed.
The heavily armoured MRAP (Mine Resistant Ambush Protected) vehicles that coalition forces use to travel in Kabul appeared to have suffered only relatively minor external damage, witnesses said.
