The Centre on Saturday announced several incentives including reserving 10 per cent vacancies in the defence ministry and paramilitary forces for Agnipath retirees as violent protests raged on against the new military recruitment scheme in many states and opposition parties stepped up pressure for its rollback.

Defence Minister Rajnath Singh, however, strongly defended the scheme saying it was brought after wide-ranging consultations and suggested a misunderstanding was being spread for political reasons, while Union Minister Anurag Thakur appealed to the youths to shun violence and come forward for talks, asserting that the government is ready to look into their grievances with an open mind and make changes, if required .

Singh also met Chief of Air Staff Air Chief Marshal VR Chaudhari, Navy Chief Admiral R Hari Kumar and Vice Chief of Army Staff Gen B S Raju and is learnt to have discussed a quick rollout of the Agnipath scheme and ways to pacify the agitators.

Mobs set ablaze Taregana railway station in Bihar during a bandh on Saturday and vandalised Ludhiana railway station in Punjab, as protesters continued to target railway properties on the fourth day of the stir and blocked roads and rail tracks in several states including West Bengal, Haryana, Rajasthan, Odisha and Uttar Pradesh.

Railways cancelled 369 trains on Saturday and passengers faced a harrowing time. Over 200 trains were cancelled a day earlier after the railways faced the brunt of the protests.

The agitation also spread to the southern states of Tamil Nadu, Karnataka and Kerala, with aspirants doing push-ups on roads at some places to register their protest.

Congress president Sonia Gandhi termed the scheme as "directionless" and said her party will work for its withdrawal while appealing to the youths to adopt peaceful and non-violent means to fight for their demands.

Party leader Rahul Gandhi said Prime Minister Narendra Modi will have to withdraw Agnipath like the farm laws.

"He will have to accept the demand of the youth of the country by becoming 'maafiveer' and take back the 'Agnipath' scheme," the former Congress chief said.

As army job aspirants staged a protest in Chennai, DMK leader and Tamil Nadu Chief Minister M K Stalin asked the Centre to rethink the scheme.

Punjab Chief Minister Bhagwant Mann demanded a rollback and said those who cleared physical tests in the last two years must get a chance to appear in written exams for joining the Army.

The Aam Aadmi Party (AAP) leader claimed that the Agnipath scheme will "dilute" the fighting ability of soldiers and render the youth jobless.

With the protesting youths alleging that they will be left in a lurch with no retirement benefits after the end of the four-year contract under the scheme, the ministries of home affairs and defence announced concessions and incentives that will assist retirees in their further employment.

The central government indicated that other departments too were working in this direction after several BJP-ruled states like Uttar Pradesh, Haryana, Madhya Pradesh and Assam announced various measures to encourage the youths to apply under the Agnipath scheme and assured them reservation.

Union Information and Broadcasting Minister Anurag Thakur said some political parties, which keep looking for every opportunity under an agenda to block any change taking place, have "provoked" the youths.

He said the government's approach on the issue is that it is ready consider any changes in the interest of the youth and the country.

"I would like to appeal to the country's youth that path of violence would not take you anywhere. ... If you have any better suggestion, you can place your views.... Government is always ready to consider with an open mind," he said and suggested the protesting youths come for talks with the central government.

The Ministry of Home Affairs (MHA) said it has decided to reserve 10 per cent vacancies for recruitment in CAPFs and Assam Rifles for Agniveers.

"The MHA also decides to give 3 years age relaxation beyond the prescribed upper age limit to Agniveers for recruitment in CAPFs & Assam Rifles," the ministry tweeted.

Further, for the first batch of Agniveer, the age relaxation will be for five years beyond the prescribed upper age limit, it said.

At present, jawans between the age of 18-23 years are recruited into the paramilitary forces.

A 10 per cent reservation will be implemented in the Indian Coast Guard and defence civilian posts, and all the 16 Defence Public Sector Undertakings, according to Defence Minister Rajnath Singh's office.

It said this reservation would be in addition to the existing quota for ex-servicemen.

"Defence Public Sector Undertakings will be advised to make similar amendments to their respective recruitment rules. Necessary age relaxation provision will also be made," it said.

The defence minister said the scheme was announced after around two years of deliberations including with the ex-servicemen community and a decision was taken based on a consensus.

"It is bringing revolutionary changes in the recruitment process in the armed forces. Some people are spreading misunderstanding about it. Maybe, there could be some confusion among the people as it is a new scheme," Singh said speaking at the conclave organised by a media group.

Union Minister Hardeep Singh Puri said the PSUs under his housing and petroleum ministries are working on hiring 'Agniveers' and also slammed the Opposition for spreading "misinformation".
