Following the Naxalite attack on CRPF personnel in Chhattisgarh's Sukma district, Odisha has sealed its border with the neighbouring state. Odisha also sounded a high alert in Malkangiri district, which is around 45 km from the site of the attack to check the influx of Naxalites. Meanwhile, Madhya Pradesh also sounded a high alert in its Naxal-affected Balaghat district.
