US envoy vows to isolate Taliban if they seize power in Afghanistan

A United States negotiator has warned the Taliban that if they seize power in Afghanistan by force, they’ll be treated as international pariahs.

Insurgent forces have now taken six provincial capitals in less than a week  and today entered a seventh.

So far the Taliban have rejected calls for a ceasefire, amid efforts to persuade them to return to peace talks and negotiate a political settlement.
