The protesting citizens, under the aegis of Patriotic People's Front of Assam (PPFA), began their march from the Guwahati Press Club shouting slogans against the outfit, carrying the national flag and raising placards.
"We want to send a strong message to ULFA(I) leader Paresh Barua that they should stop its continued disruptive activities including killing of common people in Assam," said a statement of the PPFA, a social organisation.
The rebels are eliminating Indian citizens in eastern Assam to make space for illegal Bangladeshis as a return gesture to the neighbouring country, where they had taken refuge at one time, the statement added.
