Insurgents kill four Iraqi soldiers at power plant

BAGHDAD - Insurgents killed four Iraqi soldiers in clashes outside a power plant in a southern Iraqi town on Tuesday, army sources said.
The attack in Mussayib was part of an escalated campaign of suicide bombings and shootings by guerrillas that has pressured the new government to deliver on promises of improved security.
More than 400 people have been killed in the violence since the cabinet was announced in late April following elections three months previously.
