Police and Paramilitary forces blocked another group of activists marching from Balochistan's capital Quetta to Sukkur in Sindh on Friday and arrested the Supreme Court Bar Association President Ali Ahmed Kurd along with some others.

The police action followed Thursday's incident when authorities arrested dozens of lawyers and political activists when they stopped a motorcade on way to Sukkur from Karachi.

But an undeterred Kurd, who staged a sit-in whole of the last night before his arrest, said "we have told our supporters to reach Islamabad by other routes in smaller groups."

"We are determined to go ahead with our mass protest outside the National Assembly. The march by lawyers and opposition leaders was to support reinstatement of sacked judges, but has mushroomed into a wider protest against the Government," Kurd said.
