European Commission President Jean-Claude Juncker said Sunday there was no need for a complete review of the bloc's refugee policy after the Paris attacks claimed by Islamic State jihadists.

"Those who organised, who perpetrated the attacks are the very same people who the refugees are fleeing and not the opposite. And so there is no need for an overall review of the European policy on refugees," Juncker said ahead of a summit of the Group of 20 top world economies in the Turkish Mediterranean resort of Antalya.

A Frenchman who triggered an evacuation of one of Britain's busiest airports on Saturday has been charged with possessing an air rifle and a knife, police said on Sunday.

Iran's press on Sunday largely condemned the jihadist attacks that killed 129 people in Paris and expressed sympathy for the victims, but conservative newspapers put the blame on France's policies in Syria.

Even as airlines operated a normal schedule of flights into and out of Paris on Saturday, travelers with future plans to visit the French capital reconsidered their options after a series of terror attacks.

Feeling unfairly targeted by the government's anti-radicalisation drive, Britain's Muslim community is rallying to find its own response to extremism and take a greater role in the fight against terrorism.

The Muslim Council of Britain (MCB) has planned a series of conferences around the country where community leaders, activists and others will speak out against jihadist ideology, but also government security measures they say alienates Muslims.

Costa Rica issued an urgent call Saturday for fellow Central American countries to facilitate the flow of about 1,000 desperate Cubans trying to make it to the United States.

World leaders raised the alarm over an escalating international movement of "foreign terrorist fighters" in a draft statement drawn up Sunday at a summit in Turkey after the Paris assaults claimed by Islamic State jihadists.

Myanmar's President Thein Sein on Sunday said historic polls won in a thumping landslide by Aung San Suu Kyi's party were the consequence of his government's reforms and vowed a smooth transition of power.
