Kabul, June 8 : Afghan security authorities have launched a joint security plan to contain terror threats and crimes in the national capital of Kabul, the country's Ministry of Interior said. The new plan would be conducted by the Joint Forces Command, involving forces from the ministries of interior and defence as well as the National Directorate for Security (NDS), the country's national intelligence agency to crack down hard on target killings, terrorist attacks, armed theft and other crimes, Xinhua news agency quoted quoted the Ministry as saying on Sunday. The plan which went into effect on Sunday, turned focus onto the removal of tinted films on luxury cars, forbidding the use of unlicensed vehicles and seizing illegal weapons in the city and the surrounding districts. The government vehicles would never be driven unless during official times and that the violators would legally be punished. Over the past years, Kabul with a population of nearly 5 million has been hit by series of terror attacks by the Taliban insurgents and Islamic State (IS) opposing the government. On June 2, Mohammad Ayaz Niazi, a prominent religious scholar and a Kabul university lecturer, and a civilian were killed and two people were wounded after a bomb blast hit a mosque in so-called Green Zone of Kabul. A journalist and a driver were killed and six people wounded after IS militants targeted a local TV channel's bus by a roadside bomb near a traffic circle in Kabul late last month. According to the Ministry, efforts were underway to arrest all elements behind bomb attacks in Kabul. /IANS
