Kohima, May 28 2010: Naga Students' Federation (NSF) today said it will intensify its ongoing blockade of Manipur- bound vehicles on NH-39 due to "failure" of the Manipur government in fulfilling their demands.

This decision was taken yesterday at an emergency meeting here, where it was resolved to continue the ban imposed on Manipur-bound vehicles on NH-39, which connects Imphal with Dimapur, since May 4, NSF sources said.

The federation also served an ultimatum to the Manipur government demanding withdrawal of prohibitory orders under CrPC from Naga-inhabited areas of Manipur and an unconditional apology from Chief Minister Okram Ibobi Singh for restricting NSF leaders from entering beyond the inter-state gate at Mao on May 3 .
