Defence Minister Rajnath Singh recalled the 2019 Pulwama terror attack which left as many as 40 CRPF jawans dead.
Singh attacked Congress over its remarks linking the ghastly attack to Lok Sabha elections.
"I was Home Minister when our 40 soldiers lost lives in Pulwama attack.
They (opposition) called it a conspiracy hatched by PM Modi.
We would rather sit at home than do such disgusting politics," he said.
The defence minister added that a Pakistan minister also admitted the country's role in Pulwama attack.
"Imran Khan's minister said that Pakistan was behind Pulwama," he said.
Rajnath Singh was addressing a rally in Patna's Maner constituency.
