Angry mobs in India set fire to several trains and clashed with police on Thursday during rallies against a new short-term military recruitment scheme.
Prime Minister Narendra Modi's government this week announced an overhaul of recruitment for India's 1.38 million-strong armed forces, looking to bring down the average age of personnel and reduce pension expenditure.
But potential recruits, military veterans, opposition leaders and even some members of Modi's ruling Bharatiya Janata Party (BJP) have raised reservations over the revamped process.
In eastern India's Bihar state, where protests have flared in around a dozen locations, thousands gathered in Nawada city to demonstrate against the new recruitment system, police official Gaurav Mangla said.
"They torched a BJP office, torched tyres in three prominent areas of the city, damaged a bus and many private vehicles," Mangla told Reuters.
Several other cities across India saw protests over the scheme on Thursday, with police near the capital New Delhi also using tear gas on crowds.
Police said protests also took place in northern Haryana state and western Rajasthan — both traditional recruiting areas for the Indian military.
The new recruitment system, called Agnipath or "path of fire" in Hindi, will bring in men and women between the ages of 17-and-a-half and 21 for a four-year tenure, with only a quarter retained for longer periods.
The new recruits will miss out on entitlements enjoyed by existing personnel, including government pensions, unless they are retained after the four-year programme.
Police in the eastern state of Bihar fired tear gas to disperse unruly crowds who set four train carriages alight and tried to storm government buildings.
The protests were "initially peaceful but turned violent at a few places," a senior officer in the state capital Patna told AFP. Riot police "acted carefully to avoid opening fire at the protesters. There have been no casualties or serious injuries so far," he added.
Authorities cancelled nearly two-dozen passenger train services and deployed additional police to railway stations in an effort to prevent further destruction.
