The Army thinks more British troops will be killed in fighting against Taliban forces in Afghanistan. Kick-start a discussion on the mission and its outcomes so far.

The Ministry of Defence says UK troops are in Afghanistan as part of a Nato mission to ensure the country will never again be a safe haven for international terrorism. Invite young people's reaction. How important is it to the security of the world?

A US-led bombing campaign following the 9/11 attacks drove the Taliban government from the Afghan capital Kabul. Supporters regrouped in other areas of the country, including the Helmand province where British troops are now providing "democratic, political, developmental and military assistance".

One British MP says many people in the region, including Pakistan, see British troops as an occupying army that should not be there. What do young people think is most likely to happen next?

The UK Government says it is acting partly because Afghan opium is the source of 90 per cent of the heroin used by young people in Britain. The livelihoods of the people of Helmand depend on the poppy trade. Talk about how they might react to British troops.

Other countries that have been labelled as a safe haven for many international terrorists include Somalia and Iran. Discuss why it is becoming increasingly unlikely that troops will be sent there as part of the "war on terror".
