NEW DELHI -- After a decades-long insurgency that has cost thousands of lives, India's government is vowing to eradicate Maoist guerrilla groups described as the nation's biggest internal security threat.
India's Maoist insurgency stretches back to 1967 when an armed uprising exploded in West Bengal state's remote Naxalbari village and set off the spread of Communist rebels -- commonly known as Naxalites -- to other parts of the country.
