Here are the 10 latest developments in this big story
The attack, second this year, at Kalapathar area of south Bastar region had started around 1 pm and lasted for about three hours. The Maoists had first sent locals to find out the position of the CRPF, an injured trooper, Sher Mohammad, told the media, adding that the gunbattle lasted for about three hours.
Troopers who survived the horror said the attackers in black gear used hand grenades, automatic rifles and rocket launchers as they attacked them "from all sides". "The troopers replied in a fitting manner but taking geographical position to their advantage, the Maoists succeeded in inflicting loss to the CRPF," a CRPF statement said. "A considerable number of Maoists are believed to have been eliminated," it added.
"We are working to root out the problem of Left Wing Extremism. LWE groups are anti development &they do not want development in the area," the Home Minister said today.
The injured jawans, who were air-lifted and sent to Raipur for treatment, are now out of danger, said Rajnath Singh after meeting them in hospital.
Prime Minister Narendra Modi on Monday said the attack on the patrol party of the Central Reserve Police Force (CRPF) was cowardly. "The sacrifice of the martyrs will not go in vain," he said in a tweet.
"We are yet to account for all the personnel and a search is on. Around 7 to 8 boys are still missing," news agency Press Trust of India quoted a CRPF officer as saying.
"We will forever be indebted to their selfless commitment," tweeted Chief Minister Raman Singh today. He flew back from New Delhi on Monday to hold an emergency meeting after the attack. "Sukma is Naxalite bastion. This road, once built, will cripple their network," Mr Singh had said.
Meanwhile, on the reports of 300 attackers, the acting Director General of the force, Sudeep Lakhtakia told NDTV this morning that reports "may be inaccurate" and may have been shared by jawans in a state of shock. "The total strength of a Maoist cadre in the area would not be more than 300 so the assumption is that one entire Maoist force may have been involved in the attack. However, this is an assumption," he said.
On 11 March this year, 12 CRPF men were killed and four were injured in an ambush there. The forces were providing security cover for road construction on the Bheji-Gorkha-Injiram Axis area. Since April 2010, nearly 200 security personnel have died in six major attacks in Chhattisgarh.
After the March 11 attack, Rajnath Singh said it was a sign of the "frustration" of the Maoists because of the "unprecedented success" of the security operations against them. In a statement in Lok Sabha, the minister said in 2016, 135 extremists were killed and 700 were arrested.
