The CPI(M) is observing a dawn-to-dusk hartal in areas falling under Panoor municipality to protest the crude bomb attack on its workers last evening allegedly by a group of RSS men.
Fourteen people, including four police personnel, sustained injuries in the attack which took place during a procession by CPI(M) activists at Kaivellikal, police had said.
Meanwhile, a senior police official today said 10 BJP/RSS workers were taken into custody and swords allegedly seized from them.

The incidents came days after the BJP launched the 'JanaRaksha' yatra from Kannur to highlight the "Red and Jihadi terrorism"in the state.
