Pakistan directly blamed Afghanistan and India for a deadly suicide bombing on Tuesday in Islamabad, further escalating tensions in the fragile region.

In a speech to the National Assembly on Wednesday, Pakistani Prime Minister Shehbaz Sharif blamed Afghanistan and longtime rival India for the bombing in the capital, which killed 12 people and wounded 35 others. Sharif portrayed the involvement as a pattern, further connecting India and Afghanistan to the Balochistan Liberation Army’s hijacking of a train in March, which killed 31 passengers.
