Two security personnel were killed and five injured on Monday in a suspected Maoist attack in Chhattisgarh’s Bijapur district, ANI reported. An improvised explosive device was used to target the vehicle the personnel were travelling in, said DM Awasthi, special director general for anti-Naxalite operations.

Prime Minister Narendra Modi is scheduled to visit Bijapur district on April 14. On Sunday, police had found handwritten pamphlets near a bridge, asking people to boycott Modi’s visit.

More than 30 jawans were travelling in the bus that was targeted, according to the Hindustan Times. “They were travelling from Kutru to Jangla when the bus was targeted by the Maoists,” Awasthi said. “Two jawans of district reserve guards were killed and five were seriously injured.”

The security forces are carrying out combing operations in the area, police said.

Earlier on Monday, two IED blasts were reported in the district, which were followed by an exchange of fire between Central Reserve Police Force jawans and the Maoists. One jawan received minor injuries.

Security forces found a live IED during the search operations after the exchange of fire, ANI reported.
