Security breach in Lok Sabha: Congress MP Karti Chidambaram says “Suddenly two young men around 20 years old jumped into the House from the visitor’s gallery and had canisters in their hand. These canisters were emitting yellow smoke. One of them was attempting to run towards the Speaker’s chair. They were shouting some slogans. The smoke could have been poisonous. This is a serious breach of security especially on 13th December, the day when Parliament was attacked in 2001.”
