A suicide attacker detonated a car bomb outside a compound for NATO-led troops in western Afghanistan on Saturday, killing two Afghans, officials said. Insurgents loyal to the Taliban government toppled four years ago claimed the explosion 10 metres from the gates of the Italian-led provincial reconstruction team (PRT) in the relatively calm city of Heart. The powerful blast, which was heard throughout the city, sent shards of glass flying, shattered windows of nearby houses and cracked walls, witnesses said. It left a crater in the road, which was smeared with congealed blood. A police guard at the gate and a civilian passerby were killed, NATOÂ’s International Security Assistance Force (ISAF) said. Seven other Afghan civilians were wounded, one of them seriously, and an Italian national working for a government project was lightly hurt by flying glass, Captain Giorgio Buonaiuto said in the capital Kabul.
