A suicide attack on a government office guarded by Afghan and NATO troops in eastern Afghanistan left two alliance soldiers dead and four more wounded, a US military spokesman said Tuesday. The bomber rammed an explosives-laden car into the gates of the building in the Yaqoubi district of Khost province on Monday. Sgt. 1st Class Brian Lamar, a US military spokesman, said two NATO soldiers were killed and four others wounded in the blast. Lamar would not disclose the soldiers' nationalities. However, the majority of international forces in Khost province are American.
