Afghanistan: Army chief replaced as Taliban seize more cities

Insurgents have taken control of 10 of the country's 34 provincial capitals. On Thursday the Taliban said they had taken the strategically important Ghazni city, which is on the road to the national capital Kabul. President Ashraf Ghani earlier flew to the northern city of Mazar-i-Sharif - traditionally an anti-Taliban bastion - to try to rally pro-government forces.
