Three Americans including two members of the NATO-led force in Afghanistan have been killed by homemade bombs on Saturday. The other casualty was a civilian worker. One of the soldiers died in an improvised explosive device (IED) blast in southern Afghanistan, the International Security Assistance Force (ISAF) said in a statement. In a separate incident an ISAF service member and a civilian contractor, both from the United States, died in an IED strike in eastern Afghanistan, the statement said, without elaborating.
