New Delhi (PTI): As Chhattisgarh alone accounted for over 50 per cent of casualties in the Naxal violence, Union Home Minister Shivraj Patil will undertake a tour of the worst hit areas in the state on Sunday to take stock of the situation.

Patil will tour Bastar, Bijapur and Dantewada districts to study the situation on the ground, an MHA spokesman said on Friday.

In 2007 the state witnessed the highest number of 582 incidents, against 1,530 cases reported in the other seven states badly affected by ultra-Left violence. The other states are Bihar, Jharkhand, West Bengal, Orissa, Andhra Pradesh and Maharashtra.

Chhattisgarh saw 435 killings in Naxal violence with 198 security force personnel losing their lives last year, when the total casualty figure for the affected states was 686.

During his day-long visit, Patil will tour Bastar, Bijapur and Dantewada districts where he will interact with policemen as well as villagers to take a first hand account of the situation.

In Bastar district, the Maoists have been targeting vital installations like high tension transmission lines and attacking security forces quite regularly. The ultras had damaged transmission towers located in dense forest, considered to be their hideout, last year plunging the entire area into darkness for days together.

Heavily armed Naxalites had recently struck at an iron ore plant in Dantewada district and set afire as many as 53 trucks, besides three heavy machines in a major attack on industrial facilities in the state.
