Obama tells Russia, Turkey to focus on IS

LE BOURGET: US President Barack Obama led calls Tuesday for Turkey and Russia to end their dispute over the downing of a Russian fighter jet and focus instead on the real enemy -- Islamic State jihadists.

It came as Obama's Pentagon chief said the US would increasingly rely on special operations forces to battle IS fighters in Iraq and Syria, where the extremists have seized huge swathes of territory including oil fields used to fund their activities.
