"Such senseless acts of terrorism targeting innocent lives is an attack on the democratic values of the society and deserve to be universally condemned. They must be met with determination and collective action," the president said in a message to Jammu and Kashmir Governor N N Vohra.
He called upon the Jammu and Kashmir government and all agencies concerned to ensure that the perpetrators are brought to justice and law and order is maintained in the state.
President Mukherjee has strongly condemned last night's terrorist attack on the Amarnath yatris, a press release issued by the Rashtrapati Bhavan said.
The President said: "I am sure necessary steps are being taken to provide all possible aid to the bereaved families who have lost their near and dear ones as well as medical assistance to the injured".
At least seven pilgrims died and 20 were injured in the attack.
