As 45 Assembly seats in six districts in the Maoist belt of Bihar go to polls in the second phase on Sunday, the Election Commission has changed the poll timings in some constituencies after the ultras killed six policemen in Sheohar district.

The Maoists, who triggered a landmine blast on Friday night, have given a poll boycott call.

Official sources said Maoists’ posters have appeared on government buildings and polling stations in East Champarana, Sheohar, Sitamarhi and Muzaffarpur districts.

In the wake of the blast, the EC has decided to hold polling in Sheohar and Belsand Assembly constituencies between 7:00 AM and 3:00 PM along with three other Naxal-hit constituencies of Minapur, Paroo and Sahebgunj.

Political stalwarts whose fate will be decided include state RJD chief Abdul Bari Siddiqui (Alinagar), his JD(U) counterpart Vijay Kumar Choudhary (Sarairanjan), ministers Ramnath Thakur (Samastipur) and Shahid Ali Khan (Sursand).
