Chehlum of Hazrat Imam Hussain (RA) is being observed on Thursday with religious zeal and reverence amid heightened security.
The event marks the culmination of a 40-day mourning period after the 10th of Muharram, the martyrdom date of Imam Hussain and his 72 companions in 680 A.D.
Mourning processions with Alam, Tazia and Zuljinah would be taken out in the city to mark the day.
Foolproof security arrangements have been made to provide security to Chehlum processions. The main Chehlum procession will be taken out from Haveli Alf Din inside Mochhi Gate.
Other smaller mourning processions will also be taken out from various parts of the City. A ban on pillion riding has already been imposed across Punjab.
Extra contingents of Rangers, police and police commandos have been deployed along the routes of the processions and Imam bargahs in sensitive areas in the city.
