INDIAN farmers continued their march on New Delhi today to demand minimum crop prices.

The farmers, from more than 200 trade unions and mostly from the state of Punjab, are approaching a capital ringed by razor wire, cement blocks and fencing on three sides to block their entry.

On Tuesday, police in Haryana, on the approach to New Delhi, fired tear gas on the protesters. There is no information on any casualties from the police assault.

Talks between the farmers and the right-wing Bharatiya Janata Party, led by Prime Minister Narendra Modi, broke down on Tuesday without any agreement. 

The farmers want minimum prices for their crops which allows them to sell most of their produce at government-controlled wholesale markets.

They are also demanding that the BJP government lives up to its pledge to double the income of farmers.

Farm workers leader Sarwan Singh Pandher said there were around 10,000 people at the Shambhu border that divides Punjab and Haryana, the northern states to which most protesters belong. 

Congress party leader Rahul Gandhi said on Tuesday that they would enact a law to guarantee minimum prices for the farmers if the party was voted to power in the forthcoming general election.
