About 500 experts from more than 70 nations are holding talks in Paris on how to cut off financial support for Islamic State (IS, formerly ISIS) and Al-Qaeda. Wednesday’s meeting opens a two-day international conference championed by French President Emmanuel Macron under the banner ‘No Money for Terror,’ AP has reported. The revenues of IS alone from 2014 to 2016 are estimated at $2.5 billion, according to the president’s office. The French organizers are pushing for international coordination and more transparency in financial transactions, as terrorist groups use increasingly sophisticated methods to transfer money. On Thursday, the conference will gather ministers of justice, finance, foreign affairs and the interior from Western countries, the Arab world and other nations. Representatives of 18 international organizations will also attend the event.
