New Delhi: India has launched a strong diplomatic offensive against Pakistan trying to isolate it internationally over the terror attack at the Army base camp in Uri.

Because of this, Pakistan Prime Minister Nawaz Sharif's missives to the US, UK, France, Russia and China urging them to put pressure on India over Kashmir have failed. While the US, UK and France have rejected Pakistan's claims, Russia has gone a step ahead and called off the joint military exercises with Pakistan in Pakistan-occupied Kashmir.

India has also complained about Jamaat-ud-Dawa chief Hafiz Saeed and leader of United Jehad Council Syed Salahuddin at the UN Human Rights Council, saying the terrorists were allowed to roam freely in Pakistan.

In a statement to the UNHRC, India said the fact that terrorists like Saeed and Salahuddin have been able to hold huge rallies in Pakistan's main cities is a reflection of the state of affairs in that country.

It said the active support for Saeed and Salahuddin showed that a blatant disregard for rule of law is the new normal in Pakistan and that instead of internationalising issues with India, Islamabad should cleanse its area of terrorists .

PM Sharif also met US Secretary of State John Kerry at UN and raised the Kashmir issue but Kerry, according to sources, asked him about the Uri attack.

Sharif is said to have told Kerry that the Kashmir issue can't be ignored due to one incident and that from Clinton to Obama, everyone promised a solution to the Kashmir issue. Sharif also implored the US to intervene in Kashmir, going to the extent of saying that the US as a friend of Pakistan must act.

Pakistan is having a tough time in its immediate neighbourhood as well with Bangladesh High Commissioner Syed Muazzem Ali invoking the spirit of 1971 war in pledging support to India.

"It's a sensitive military issue. As close neighbours and ally and friends we will act together. Bangladesh will help India. As a freedom fighter of 1971, we fought with the Indians together during our war of liberation, I want the spirit of 1971 to remain in our relations."

Supporting India in the war against terror, Afghan Ambassador to India Shaida Mohd Abdali said, "We condemn this strongly. We fully support Prime Minister Narendra Modi's call for strong action against those countries that use terrorism as foreign policy."

After India's diplomatic offensive, sources said the Narendra Modi government will not react in a kneejerk fashion but surgical strikes and targeting Pakistan terror bases is an option.

The proof against Pakistan is undeniable as ammunition found on the terrorists in Uri attack have Pakistan markings. They were also carrying food items made in Karachi.

Among the arms and ammunition recovered in Uri were 39 UBGL grenades, five hand grenades, two radio sets, two GPS devices, two maps and "large quantities of food and medicines with Pakistani markings on them", DGMO Lt General Ranbir Singh said.

Eighteen soldiers lost their lives in the worst terror attack on an Army camp in a decade.
