Indian Prime Minister Narendra Modi warned Pakistan on Friday that India will respond decisively to any future attacks, as the country celebrated its 78th Independence Day.

Speaking from the historic Red Fort in New Delhi, Modi said India has established a "new normal" that makes no distinction between "terrorists" and those who support them. He vowed that India would no longer tolerate what he called Islamabad’s "nuclear blackmail."

"For a long time, nuclear blackmail had been going on, but this blackmail will not be tolerated now," Modi said.

The warning comes three months after India and Pakistan, both nuclear-armed rivals, fought their worst clashes in decades during four days of intense fighting.

There was no immediate response from Pakistan, which has previously dismissed India’s statements on nuclear threats as provocative and inflammatory.
