Una (Gujrat): Thousands of Dalits today took a pledge not to remove cow carcasses and to launch a rail roko stir if five acres of land for each family is not granted by Gujarat government within a month even as tension broke out after an attack in which eight of them were injured.

As the 10-day long 350-km foot march from Ahmedabad culminated at the epicentre of Dalit protests here, some dalits returning after the conclusion of the rally that coincided with the 70th Independence Day were attacked by suspected upper caste people in Samter village in Una in Gir Somnath district.
