By Aftab Ahmed, Shivam Patel and YP Rajesh NEW DELHI/ISLAMABAD (Reuters) -Indian Prime Minister Narendra Modi warned Pakistan on Monday that New Delhi would target "terrorist hideouts" across the border again if there were new attacks on India and would not be deterred by what he called Islamabad's "nuclear blackmail".

Indian Prime Minister Narendra Modi spoke after Indian and Pakistani authorities said there was no firing reported overnight along the heavily militarized region between their countries.

The neighbors had agreed to a full and immediate cease-fire in the worst violence between them for more than two decades.
