LONDON, Aug 2, 2009 (AFP) - Talks aimed at bringing about peace in Afghanistan must be "all-inclusive" to succeed, the top UN official to the country said in comments published here Sunday.

"If you engage partially you will have partial results," Kai Eide, head of the UN Assistance Mission in Afghanistan (UNAMA), said in an interview with The Sunday Times.

"We have to have a political process that is all-inclusive. That's the only way to bring this conflict to an end."

He added: "If you want important results you need to talk to people who are important.

"We won't get where we want by negotiating with local commanders on the ground. That's an inadequate peace process and that won't work."

There are more than 100,000 international troops in Afghanistan mainly deployed under NATO and a separate US-led coalition that is trying to tackle mounting violence from a Taliban-led insurgency.
