Afghan forces backed by US aircraft have launched a counter-offensive to retake the city of Kunduz.
The provincial capital was overrun by Taliban fighters on Monday.
Witnesses say the streets were littered with bodies
as Taliban fighters screeched round the city in stolen vehicles.
The group broke open the local jail and freed 500 inmates, many of them Taliban members.
Afghan troops retreated to the airport to regroup.
The Taliban’s military success will pile pressure on President Ashraf Ghani.

Kunduz is a key transport hub linking the north of the country and a former Taliban stronghold.
It is the first major city to fall into Taliban hands since the US-led invasion forced the Taliban from power in 2001.
