New Delhi: The CRPF on Tuesday killed 20 ultras in Chhattisgarh's Bijapur district in extensive anti-Naxal operations, weeks after dozens of jawans were gunned down in a Maoist ambush, considered one of the deadliest in recent years.

According to CRPF, around 350 jawans are taking part in the operations.

Citing the CRPF IG, ANI reported that for the first time COBRA batallions have been deployed.
