India has summoned Pakistan's high commissioner in New Delhi to protest against what it said was the continued infiltration of militants from across the border.
"The government of India strongly protests against the continued infiltration from Pakistan of trained terrorists with instructions to carry out attacks," the Foreign Ministry said on August 9.
It said an arrested Pakistani national, Bahadur Ali, had confessed that he was "infiltrated into India" after being trained by the Lashkar-e-Taiba (LeT) militant group.
Pakistan's Foreign Ministry said Islamabad was committed to not allowing the use of its territory for any militant activity against anyone.
India and Pakistan have fought three wars, two over control of Kashmir, since they won independence from Britain in 1947.
India accuses Pakistan of training and arming militants in the portion it controls and sending them to the Indian side, something which Islamabad denies.
