Paris attacks: Hollande and Obama to intensify anti-IS push
The fight against so-called Islamic State (IS) will dominate talks in Washington shortly as French President Francois Hollande meets US President Barack Obama.
The Paris suicide attacks claimed by IS have prompted the US to issue a worldwide travel alert to its citizens.President Hollande is meeting other world leaders this week, hoping to forge a stronger alliance against IS.
But Turkey's downing of a Russian jet has fuelled tension over the Syria war.
As Turkey is a Nato member the incident has put a new strain on Russian-Western efforts to neutralise the IS threat in Syria and Iraq.
The US is unlikely to support French efforts to build a Russian-Western military alliance against IS, correspondents say. But there is some military co-ordination with Russia.
France is now sending warplanes from the aircraft carrier Charles de Gaulle, off the Syrian coast, to pound IS targets.
