Jammu: A protester was killed and over a dozen others, including three policemen, were injured on Thursday in clashes between security forces and a group of Sikh who blocked roads here on Thursday denouncing the removal of a poster carrying picture of militant Sikh leader Jarnail Singh Bhindranwale.

Police sources said security forces had to open fire to quell a violent mob of Sikh protesters at Gadigarh, eight km from Jammu city centre.
