Pakistan's filing of terror charges against Lashkar-e Taiba chief Hafiz Saeed and the assurance of his arrest is a "cosmetic step" and Islamabad is not doing enough to control terrorists acting from the country, the Centre said today. Hafiz Saeed, the chief of Lashkar-e Taiba and the mastermind of the 2008 Mumbai terror attack, has been getting a free run in Pakistan even after India provided Pakistan with the evidence.
