Tensions between longtime political, territorial, and ideological foes, India and Pakistan, are escalating.

The current crisis began when Pakistan-based terrorists killed 26 Indian tourists in an April 22 attack in the disputed Jammu and Kashmir region. On Wednesday, India launched retaliatory air strikes against terrorists inside Pakistan that it blames for the attack. Pakistan then appears to have responded with drone attacks on Indian territory on Wednesday. India has subsequently responded with its own counter-retaliation, and both sides are now engaged in limited but growing conflict.
