Police say they have launched a rescue operation for seven road construction workers kidnapped by Maoist rebels in eastern India.
They say dozens of rebels seized the workers on Friday as they were building a bridge in Bihar state's southeastern Jamui district.
Police official Puskar Anand said Saturday that the district's borders have been sealed and authorities believe the workers are being held in a remote jungle hide-out.
Last week, the rebels killed 11 people and attacked police stations, railway lines and a school building. The government considers them to be the country's greatest internal security threat.
The rebels are inspired by Chinese revolutionary Mao Zedong and have fought for decades for land and jobs for farmers and the poor.
