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.

Hours after the cease-fire was confirmed, there were accusations that the agreement was not being entirely upheld.
