Now, three of Pakistan's 4 neighbours have accused it of exporting terror and harbouring terrorist organizations.
The latest to make the accusations is Iran, which warned Pakistan that it would carry out "surgical strikes" against Sunni terror groups from Pakistan that are responsible for several attacks inside Iran.
Pakistan's primary export: Terror
What was the issue about?
10 Iranian border guards were killed last month when Sunni militants from the Jaish al Adl fired upon Iranian border outposts with long range weapons from inside Pakistan.
They have done this before as well, when they killed 8 border guards in 2015 and 14 in 2013.
In 2014, 5 Iranian border guards were kidnapped by the group, who released 4 and killed 1.
Who are Jaish ul-Adl?
Jaish ul-Adl (Army of Justice) is a Sunni terror group fighting for independence in Iran's Sistan-Baluchestan province. It fights against the rule of a Shia theocracy on a Sunni population.
