America is set to ask its NATO allies to send thousands of extra personnel to train Afghanistan's new army and police force. The U.S. says the aim is to stabilise the troubled country, but at the same time is planning to launch the biggest offensive since entering eight years ago. Defence ministers from NATO member nations, are meeting in the Turkish city of Istanbul. The U.S. wants around four thousand extra troops from them, on top of the nine thousand already pledged. America is sending 30 thousand extra combat troops of its own. But locals fear more troops will mean more Taliban attacks.
