AMSTERDAM - The Islamic State group has honed the ability to launch global attacks and is set to focus more on Europe following the Paris massacre, the chief of the EU police agency Europol said Monday.
Rob Wainwright told a news conference that "the so-called Islamic State had developed a new combat style capability to carry out a campaign of large-scale terrorist attacks on a global stage - with a particular focus in Europe."
"So-called Islamic State has a willingness and a capability to carry out further attacks in Europe, and of course all national authorities are working to prevent that from happening," he added.
Wainwright was unveiling the findings of a new Europol report on changes in how the militant group operates, coinciding with the launch of the agency's new counterterrorism centre in The Hague.
IS claimed responsibility for the November 13 Paris attacks in which 130 people were killed, releasing a video on Sunday purporting to show nine of the militants in which they threaten "coalition countries" including Britain.
A US-led coalition has been fighting IS in Syria and Iraq since September 2014.
"IS is preparing more terrorist attacks, including more 'Mumbai-style' attacks, to be executed in member states of the EU, and in France in particular," the Europol report said.
"The attacks will be primarily directed at soft targets, because of the impact it generates. Both the November Paris attacks and the October 2015 bombing of a Russian airliner suggest a shift in IS strategy towards going global."
Meanwhile, France and Britain on Monday dismissed a video released by the Islamic State group showing militants who carried out the November Paris attacks training and committing atrocities in what is likely Iraq or Syria.
Two months after IS gunmen and suicide bombers attacked Paris nightspots, killing 130 people, the group published a 17-minute video showing four Belgians, three French citizens and two Iraqis all of whom took part in the assault and either died on the night, or in a subsequent police raid days later.
Entitled "Kill wherever you find them", the video shows nine men delivering final messages inciting lone-wolf attacks and, in particular, threatening Britain.
Seven are shown outdoors behind victims who are later decapitated or shot, while another is seen carrying out target practice.
Purported ringleader Abdelhamid Abaaoud, who was in Europe for several months before the attacks, is the only one speaking inside a room.
The fighters' battlefield names are given, and the video confirms for the first time that IS trained the attackers and sent them to carry out the assault, rather than merely inspiring supporters from afar.
"The clear preparation that went into it... specifically highlights how this was a plot that was directed by core IS," said Raffaello Pantucci of the Royal United Services Institute (RUSI) in London.
"The dilemma has always been: was IS actually employing assets against the West or was it just creating noise to throw sand in our faces? Now it's quite clear they are attacking."
The video features images of French President Francois Hollande and British Prime Minister David Cameron with targets superimposed on them.
Referring to the 70-nation coalition fighting IS, Abaaoud warns that "the more you wage war against the Islamic State, the more it will expand... for we are terrorists." But Hollande, who is on a visit to India, dismissed the threats.
"Nothing will deter us, no threat will make France waver in the fight against terrorism," he told reporters. And Cameron's office said the video showed "an appalling terrorist group that's clearly in decline and in retreat."
With French and Arabic songs playing in the background, the video calls for the murder of Westerners, and names two of the Paris streets where several of the attacks took place.
It also praises Amedy Coulibaly, who killed four hostages at a Jewish supermarket in January 2015, two days after the Kouachi brothers staged a deadly attack on the Charlie Hebdo magazine, killing 12.
The video, produced by IS's Al-Hayat Media Centre, shows television news footage of the night of the attacks, and the chaos in Paris, with red targets superimposed over special forces in the streets of the French capital.
It was not clear why the video was released more than two months after the devastating attack, but Pantucci suggested it was merely a tactic to "reclaim the news agenda again".
In a report released on Monday, the European police agency Europol warned IS was planning more attacks on soft targets in the EU.
IS has developed an "external action command" which was trained for "special forces-style attacks" internationally, the report said.
It is still not clear how many people were involved in the assault on Paris in which seven assailants blew themselves up or were shot dead by police.
Two of them, who blew themselves up outside the national stadium and were found with fake Syrian passports, could be the two Iraqis shown in the video.
Abaaoud, thought to have previously fought in Syria, was killed in a shootout with French police days after the bloodiest attacks to hit Europe since the Madrid train bombings in 2004.
Hollande has said the attacks were planned in Syria, but prepared and organised in Belgium.
Belgian authorities have formally charged 10 people in the case, including a number from the troubled Brussels neighbourhood of Molenbeek where several of the attackers had lived.
Four suspects remain at large, including Salah Abdeslam, who was present on the night but whose role remains uncertain, as well as Mohamed Abrini, suspected of having helped scout out targets. Both are from Molenbeek.
The video makes no reference to Salah, whose brother Brahim blew himself up in the attack.
