The blame game began only hours after President Trump announced Saturday that the U.S. had mediated an immediate ceasefire.

Vice President Vance said the fighting between India and Pakistan was "fundamentally none of our business." Experts say the U.S. used to work hard to de-escalate crises between the nuclear states.

The escalation began after India accused Pakistan of being behind an attack where gunmen killed 26 people, mostly tourists, in India-administered Kashmir on April 22. Pakistan denies it.

Pakistan says India's strikes on Wednesday is "an act of war." India's military described its operation as targeting "terrorist infrastructure."

India has launched strikes in several parts of Pakistan and Pakistan-controlled territory, in a dramatic escalation of tensions between the two nuclear-armed rivals.
