"We welcome the opening of the Taliban office in Qatar, and we are happy about it," Mullah Ehsanullah, a local Taliban fighter in the Zherai district of the southern province of Kandahar, told AFP by telephone.

"With the establishment of this office, we want to hold talks with the international community like an independent and sovereign state,” he said.

"We are reaching our goals in defeating the US, now we want to free our country from occupation. We want to build our country on our own."

The opening of the office in Qatar for Taliban which is a feared terrorist group in Afghanistan for its brutal extremist acts against people, has raised condemnation of Kabul arguing that they are posing as a government-in-exile.

When the office opened on Tuesday, it used the title of the rebels' 1996-2001 government, the "Islamic Emirate of Afghanistan", and flew the white Taliban flag -- a provocative symbol of oppression to many Afghans.

On Wednesday, Afghan lawmakers voiced their strong opposition to the opening of the controversial office in Doha.

The Afghan government suspended all strategic talks with Washington to discuss the nature of US presence after foreign troops withdraw in 2014.

The United States and its allies invaded Afghanistan in 2001 as part of Washington’s so-called war on terror. The offensive removed the Taliban from power, but after almost 12 years, insecurity remains across the country.
