India launched military strikes on Pakistan on Wednesday and Pakistan claimed it shot down five Indian Air Force jets, in an escalation that has pushed the two nations to the brink of a wider conflict.

New Delhi controls around 172 nuclear weapons, according to the Arms Control Association. Pakistan has approximately 170 nuclear warheads. India and Pakistan, two nuclear-armed nations, saw a decades-old conflict reignite May 7 as a terror attack in the disputed region of Kashmir led India to carry out cross-border airstrikes.
