NEW DELHI (AFP) - The power grab by Taliban insurgents in Pakistan puts the nations future at a crossroads, according to Frances new special envoy to Afghanistan and Pakistan. With the Taliban having advanced to districts just 100 kilometres from the capital, Pakistan has a fire inside its own house that it must extinguish, said lawmaker, lawyer and foreign policy expert Pierre Lellouche. There is not a lot of time in light of the gravity of the situation, he told reporters in New Delhi late Thursday after visiting Islamabad on a fact-finding mission. Pakistan is at a crossroads, he said, saying the country faced an existential question about its future existence. His remarks came as Pakistans army launched this week an offensive to reassert control in the northwest of the country. They were the latest expression of international concern about the situation in Pakistan, led by the United States which last week accused Pakistans government of abdicating to the Taliban by agreeing to Sharia law in parts of the country. The Swat agreement has a worldwide resonance, said Lellouche who met President Asif Zardari and Army Chief Ashfaq Parvez Kayani during his visit to the Pakistani capital. He said he did wish to be alarmist but there was a risk of a Talibanisation of Pakistan and that the civilian government could lose control of the country. The Talibanisation has begun, said Lellouche, who held talks with senior Indian officials during his stopover here to discuss the regional situation before returning to France. Zardari has said the country is facing a critical hour in its fight against insurgents linked to Al-Qaeda. In naming Lellouche as a single envoy for Pakistan and Afghanistan in March, Paris followed the example set by Britain, Germany and the US, which also have senior diplomats overseeing their response to the crisis. In a letter of appointment for Lellouche, French President Nicolas Sarkozy told him he had a free hand to propose any initiative that you consider useful for Frances interests. France is the fourth largest contributor to the 70,000-strong US and NATO force deployed in Afghanistan.
