Roadside bomb kills 2 Afghan security guards

A roadside bomb killed two Afghan security guards working for a US military base in eastern Afghanistan, and police separately shot and killed a would-be suicide bomber, officials said Wednesday. The guards were traveling in Khost province's Yaqoubi district Tuesday when an explosion from the roadside device ripped through their vehicle, said Wazir Pacha, a spokesman for provincial police chief. Police in the same province killed a would-be suicide bomber who was carrying hand grenades as he tried to enter a police checkpoint Tuesday, Pacha said.
