The Paris attacks and the discovery of a Syrian passport near one of the assailant's bodies have revived the European debate on whether to take a harder line on migrants.

With the continent facing its biggest migration crisis since World War II, EU states have bickered for months on how to stem the flow and share out the new arrivals.

Several foreigners have been identified among the victims of Friday's deadly terrorist attacks in Paris, which left at least 129 dead and more than 350 injured:

According to an AFP tally from various official sources around the world, at least 23 foreigners lost their lives in the attacks.

The suicide vests used by Friday's attackers in Paris -- a first in France -- were made by a highly skilled professional who could still be at large in Europe, intelligence and security experts say.

All seven of the militants wore identical explosive vests and did not hesitate to blow themselves up -- a worrying change of tactic for jihadists targeting France.

Simultaneous attacks on multiple targets by gunmen and suicide bombers working in unison: a nightmare scenario that France's anti-terror agencies had dreaded for months came true in Paris on Friday night.

Security officials and experts have predicted that an unprecedented attack was in the offing, and would be nigh impossible to thwart.

Boosted by an election victory, Turkish President Recep Tayyip Erdogan wants to use the G20 summit to remind the world of his status as a global leader and consolidate his domestic popularity.

Commentators began writing Erdogan's political obituary when his Islamic-rooted ruling party lost its outright majority in June elections for the first time since it swept to power over a decade ago.

The Syrian army's decision to repeatedly extend tours of duty and aggressive recent conscription campaigns are stirring anger online and in private conversations among pro-regime Syrians.

Depleted by years of conflict, with its ranks approximately halved, the army has been forced to keep conscripts on well past their usual two years of service.

The stunning victory of President Recep Tayyip Erdogan's party in legislative elections has plunged the Turkish opposition into disarray, leaving it fighting simmering rebellions and baffled over how to challenge the strongman leader.

Leaders of the traditional opposition parties are all under pressure after failing to stop the Justice and Development Party (AKP) in its tracks on November 1, when it defied pollsters' expectations and regained an overall majority.

An increasingly popular route for migrants across Russia and into Norway has Oslo angered and worried as winter approaches, while commentators suspect Moscow is deliberately creating problems for its neighbor.

Since the start of the year, around 4,000 asylum seekers have made a long detour through the far north to cross the border between Russia and Norway, which is a member of the Schengen agreement on free movement even though it is not a member of the European Union.

Last month's deadly Russian jet crash in Egypt has plunged the north African tourist industry further into crisis, with resorts seen as less risky now likely to benefit from the shifting travel patterns, experts said.

Sunseeking travelers are also likely to place particular emphasis on the reputation of particular airports when making plans, although attractive prices are certain to still be a major factor.

Catalonia may have voted to kick off a process towards independence but the wealthy region is far from breaking up with Spain, and Prime Minister Mariano Rajoy could actually benefit in upcoming elections, experts say.

Lawmakers in Catalonia officially started a process Monday to secede from Spain by 2017 in an unprecedented showdown with Madrid, after a parliamentary majority voted for a pro-independence resolution.
