The top British commander in Afghanistan says the West should have tried to strike a deal with the Taliban when it was toppled a decade ago.

General Nick Carter says a political solution would have been much easier to find with the militant group "on the run".

But the general also said he was optimistic about Afghanistan's future, as long as the US and its allies keep supporting the country. There are 8,000 British troops still serving in Afghanistan.
