India farmers say barricades won't stop Delhi march, they would use heavy machinery

Protesting Indian farmers are resuming their march on capital Delhi after four rounds of talks with the federal government failed to end the deadlock.

The farmers, who are demanding assured prices for their crops, say are coming prepared with months of supplies.

Delhi's borders have been fortified with layers of barricades, concrete blocks and barbed wires to stop their entry.

But protesters have warned they would use heavy machinery to push through.
