US envoy links Haqqani militants to Pakistan government

There is evidence linking the Haqqani militant network to Pakistan's government, the US ambassador to Pakistan has said in a radio interview.

"This is something that must stop," Cameron Munter told Radio Pakistan, when discussing Tuesday's militant assault on the Afghan capital, Kabul.

At least 25 died during a 20-hour-long attack blamed on the Haqqani group, who are believed to be based in Pakistan.

Pakistani authorities have consistently denied links with militant groups.
