Skies darkened after Paris terror attacks, Barack Obama says
US President Barack Obama says the terror attacks in Paris were an "attack on the civilised world" and that "the skies have been darkened" by the incidents.
Mr Obama is pledging US solidarity with France in the effort to hunt down the perpetrators and bring them to justice.
He made the comments in a meeting with Turkish President Recep Tayyip Erdogan on the sidelines of the G20 economic summit featuring leading industrial and emerging-market nations.
Mr Erdogan says there will be a "strong message" on fighting terrorism coming out of the summit.
Mr Obama also said the US stands with Turkey and Europe in the effort to reduce the flow of migrants. He says the US and Turkey will redouble efforts to resolve Syria's civil war.
