Taliban fighters could isolate Afghanistan's capital in 30 days and possibly take it over within 90, a US defence official cited US intelligence as saying, as the resurgent militants made more advances across the country.<br /><br />The official, speaking to Reuters on condition of anonymity on Wednesday, said the new assessment of how long Kabul could stand was a result of the Taliban's rapid gains as US-led foreign forces leave.<br /><br />"But this is not a foregone conclusion," the official added, saying that the Afghan security forces could reverse the momentum by putting up more resistance.
