How LS security breach revived memories of 2001 attack

A security breach occurred in Lok Sabha, reviving memories of the 2001 Parliament terror attack. Two men jumped into the chamber and released yellow gas while shouting slogans. Two others sprayed colored gas outside. The attackers were overpowered by MPs and handed over to security personnel. The 2001 attack involved terrorists from Lashkar-e-Taiba and Jaish-e-Muhammed. It is unknown if the protesters in the recent incident were affiliated with any group, but a Khalistani terrorist had threatened to attack Parliament.
