Roadside bomb kills six in Baghdad - police source

BAGHDAD, June 12 (Reuters) A roadside bomb targeting a bus carrying oil ministry workers killed six people and wounded 12 others in Baghdad today, a police source said.

The bus was on its way to an oil refinery in the capital's southern Dora district when the bomb detonated.

Insurgents often mount bomb attacks as part of a campaign to topple the US-backed, Shi'ite-led government.
