Defense Minister Nirmala Sitharaman said on February 12 that the Indian military had evidence proving that 'these terrorists were being controlled by their handlers' from Pakistan.
Sitharaman said the February 10 attack left at least five soldiers and one civilian dead and 11 other people injured. Three militants were also killed.
The Indian minister said that the gunmen belonged to the Pakistan-based militant group Jaish-e Mohammed.
'Pakistan is expanding the arc of terror...resorting to cease-fire violations to assist infiltration,' she said.
Meanwhile, Pakistan's Foreign Ministry rejected all 'insinuations' from Indian officials.
'We are confident that the world community would take due cognizance of India's smear campaign against Pakistan, and the deliberate creation of war hysteria,' a statement said.
In continuing violence in the Himalayan territory, one paramilitary soldier was reported killed on February 12 when gunmen opened fire near a paramilitary camp in India-administered Kashmir.
Kashmir has been divided between India and Pakistan since the end of British rule in 1947. Both claim the region in its entirety and have fought two wars over it.
New Delhi frequently accuses Islamabad of arming, training, and sending fighters across the Line of Control to launch attacks on its soldiers in Kashmir.
Pakistan denies the allegations, saying it only provides diplomatic support to the Kashmiri struggle for right to self-determination.
