( CNN ) Several terror attacks . Deadly counterterrorism raids . And a wave of suspected jihadist arrests from France to Greece to Belgium . European Union officials are scrambling to stop the spread of terrorism and threats , with foreign ministers meeting Monday in Brussels , Belgium , to tackle the issue . `` We start with obviously a discussion on how to counter terrorism , not only in Europe but also in other parts of the world , '' said Federica Mogherini , EU high representative for foreign affairs . She said she had just met with Arab League Secretary-General Nabil el-Araby `` as the threat is not only the one we faced in Paris , but also spreading in many other parts of the world starting from Muslim countries . `` And we need to strengthen our way of cooperating together , first of all with Arab countries , and then internally . '' With new developments sprouting up across Europe , here are the latest : . • The hunt is still on for the ringleader behind a terrorist cell targeted in raids last week , Belgium 's justice minister said . The suspected leader and key link between senior ISIS operatives in Syria and the Belgian terrorist cell , Belgian-Moroccan ISIS fighter Abelhamid Abaaoud , is still at large , a senior Belgian counterterrorism official said . Abaaoud 's last known location was believed to be Greece , the official said . • An Algerian national who may have links to Abaaoud was arrested over the weekend in Greece and is being extradited to Belgium . • The man detained by Belgian police after last week 's raid has been identified . His attorney says he is n't a terrorist ; he was just delivering shoes to a friend when he was caught in the wrong place at the wrong time . But investigators believe the man played a key role in the terrorist cell 's plot , the Belgian counterterrorism official said . • Investigators are looking for a man whose DNA was found on a gun magazine used by Amedy Coulibaly , who killed four hostages at a kosher supermarket in Paris . • Sales of counterfeit goods by Charlie Hebdo attacker Cherif Kouachi helped fund the purchase of weapons , a source familiar with the ongoing investigation in France told CNN . Five Belgian nationals have been charged with participation in a terrorist organization in connection with last week 's raid in Verviers , federal prosecutor Eric Van Der Sypt said . The terror cell planned to target police officers , he said . Belgian counterterrorism agencies think the suspected ringleader of the cell is likely Abaaoud , the senior Belgian counterterrorism official said . According to Guy Van Vlierden , a reporter at the Belgian newspaper HLN who tracks Belgian foreign fighters in Syria for the blog `` emmejihad , '' Abaaoud is a 27-year-old from the Molenbeek district of Brussels who traveled to Syria in January 2014 and joined ISIS soon afterward . The two gunmen killed in the Verviers raid , Belgians of North African descent from the same Brussels district , were in phone contact with an ISIS ringleader in Greece , who Belgian authorities believe was likely Abaaoud . But Belgian authorities have not ruled out the possibility that an Algerian suspect arrested in Greece over the weekend was the key link between the terror cell and ISIS . That 33-year-old suspect was wanted in Belgium on charges of terrorist activity , Greek police said Monday . Belgium is requesting an extradition . And Greece is n't done yet ; police there say they have made multiple arrests and are looking for more suspects . Other countries are also helping Belgium nab suspected jihadists . French authorities captured two suspects as they were trying to cross from France into Italy , Van Der Sypt said . Four days after police raided a suspected terror cell in Verviers , Belgium , killing two people who authorities said were part of a terrorist cell on the brink of a major attack , we now know the name of the surviving suspect . Marouane El Bali was taken into custody and faces charges of participation in a terrorist organization and possession of explosives with intent to commit a criminal attack , among other charges , said his attorney , Didier De Quévy . But De Quévy said his client was not involved in any terrorism . `` He went to Verviers to see his fiancée and was dropping off a pair of sneakers , '' De Quévy said . `` He did not know that these guys were connected to international terrorism . He arrived , he sat down and , the moment he sat down , the policemen starting shooting . He managed to escape by jumping out the window . The other two , however , took their guns and responded and got killed . '' Authorities say it was n't just a case of being in the wrong place at the wrong time . Investigators believe El Bali played a key role in the terrorist cell 's plot and was a key intermediary between two dead gunmen and a wider network in Brussels , the senior Belgian counterterrorism official said . El Bali is also believed to have fought with ISIS in Syria at some point . There are still concerns that part of the terror cell remains at large in Belgium , and could take revenge for the death of their comrades , the senior counterterrorism official said . Belgian security services suspect around 10 people were involved in the cell , but they do n't know the number for sure and that worries them . Belgian counterterrorism officials believe the cell had ambitious attack plans beyond attacking police , given bomb-making chemicals found in their safe house in Verviers and police uniforms . They also suspect terrorists were plotting multiple attacks . The belief is that the cell has now been disrupted and will take some time to get back on its feet . The wider cell was being monitored for less than two months . Over the last several weeks , Belgian security services started monitoring the Verviers group 24/7 . Why did police move in last week ? One reason , the official said , is that the cell obtained weapons and Belgian police could not continue round-the-clock surveillance indefinitely . Investigators say DNA found in a car used to transport Jewish market attack gunman Coulibaly has been traced to a man who is already in custody in connection with the attacks , according to a source familiar with the ongoing investigation . Investigators are still looking for a person whose DNA was found on a magazine for Coulibaly 's gun . Coulibaly is the gunman who killed four hostages on January 9 at a kosher grocery store in Paris before police killed him . Before the siege , he had proclaimed his allegiance to the Islamic State in Iraq and Syria , or ISIS . The assault happened during three days of terror in France that began with the attack on offices of the Charlie Hebdo satirical newspaper in Paris . In all , 12 people died in the Charlie Hebdo attack on January 7 . Al Qaeda in the Arabian Peninsula , al Qaeda 's Yemen affiliate , claimed responsibility for the Charlie Hebdo shootings . On Monday , CNN affiliate BFMTV reported Charlie Hebdo cartoonist Laurent Sourisseau will succeed editor Stephane Charbonnier , who died in the attack . Although French officials said they thought Cherif Kouachi had given up terror-related activities and moved to end surveillance on him after he began selling counterfeit goods , it turns out the proceeds from those sales were being used to buy weapons , a source familiar with the ongoing investigation in France told CNN . That 's just one of several missteps by intelligence agencies in France being revealed by the investigation into the attacks , the source said . Other failings include a lack of communication and delays in circulating information , according to the source . In one case , a French surveillance agency received an alert about one of the Kouachi brothers ' phones in February 2014 , but it took four months for information to be passed on to the country 's main domestic spy agency , the source said . By then , neither brother was under surveillance , the source said . The surveillance on Cherif Kouachi ended in November 2013 ; the surveillance on Said Kouachi , the older brother , ended in June , sources have told CNN . Also , authorities now say they think both Said and Cherif Kouachi traveled to Yemen in 2011 via Oman , even though Cherif 's passport had been confiscated in 2010 . However , investigators have been unable to find either brother 's name in travel databases , according to the source . CNN 's Phil Black , Ivan Watson and Catherine E. Shoichet contributed to this report .
