A "new phase" in the international mission in Afghanistan. That's the call from German Chancellor Angela Merkel and Afghan president Hamid Karzai ahead of a security conference in London tomorrow.

But first there will be an INCREASE in foreign troop numbers - with Germany sending hundreds more soldiers to the country.
