Gunfire erupts near Paris stadium as police hunt fugitives

Several suspected attackers and potential accomplices remained holed up in an apartment after the shoot-out, the source said.

Friday night's attacks in the French capital, claimed by Islamic State militants, raised security concerns around the world, with an international football match called off in Germany and two Air France flights from the United States diverted.

In Syria, France and Russia bombed targets to punish Islamic State for the coordinated Paris massacre and the downing of a Russian airliner over Sinai on Oct. 31.

French TV stations BFMTV and iTele both showed amateur video of Wednesday's early morning shooting and cited witnesses in the area as saying they had heard sporadic gunfire from around 4:30 a.m. (0330 GMT).

BFMTV said some police had been wounded during the operation, which took place near the Stade de France sports stadium where three suicide bombers detonated their explosive belts and killed a passer-by on Friday.

French prosecutors have identified five of the seven dead assailants from Friday - four Frenchmen and a man who was fingerprinted in Greece among refugees last month.

But they now believe two men directly involved in the assault subsequently escaped.

Wednesday's operation came after a source with knowledge of the investigation said a cell phone had been found with a map of the music venue targeted in one of the attacks and a text message on it saying words to the effect of "let's go".

The source said the phone was found in a dustbin near the Bataclan concert hall where the bloodiest of the shootings took place.

Islamic State said it carried out the attacks in retaliation for French and Russian air raids in Iraq and Syria. Investigators said the Paris plot was hatched in Syria and nurtured in Belgium.

Late on Tuesday, the U.S. Federal Aviation Administration (FAA) said two Paris-bound Air France flights were diverted following anonymous bomb threats, and hundreds of passengers and crew were safely removed.

Flight 65, an Airbus A-380 that had departed from Los Angeles, landed safely in Salt Lake City where passengers and crew were escorted into the terminal, an FAA spokesman said.

A separate flight that left Dulles International Airport outside Washington, D.C., Flight 55, was diverted to Halifax International Airport in Nova Scotia, Canada, where passengers and crew had also disembarked. The Halifax Airport tweeted that 262 passengers and crew members had been aboard.

In a brief statement, Air France said both flights had been the "subjects of anonymous threats received after their respective take-offs".

Earlier, bomb fears had prompted German police to call off a football match between Germany and the Netherlands in Hanover two hours before kick-off. German Chancellor Angela Merkel had been due to attend.

No arrests were made and no explosives were found.

"We had received specific indications that an attack with explosives was planned," Hanover Police President Volker Kluwe told NDR state broadcaster. "We took them seriously, and that is why we took the measures."

France and Germany were playing a football friendly at the Stade de France when Friday's attacks took place.

Syrian targets hit by Russian long-range bombers and cruise missiles on Tuesday included the Islamic State stronghold of Raqqa. French warplanes also targeted Raqqa on Tuesday evening in the third such bombing raid within 48 hours.

Paris and Moscow are not coordinating their operations, but French President Francois Hollande has called for a global campaign against the radicals in the wake of the Paris attacks.

Russian President Vladimir Putin vowed to hunt down those responsible and intensify air strikes against Islamists in Syria.

The Kremlin said Putin spoke to Hollande by telephone and had ordered the Russian navy to establish contact with a French naval force heading to the eastern Mediterranean, led by an aircraft carrier, and to treat them as allies.

"Maybe today this grand coalition with Russia is possible," French Defence Minister Jean-Yves Le Drian told TF1 television channel on Tuesday evening.

Hollande will visit Putin in Moscow on Nov. 26, two days after the French leader is due to meet U.S. President Barack Obama in Washington to push for a concerted drive against Islamic State, which controls large parts of Syria and Iraq.
