The 15-nation Security Council also stressed the need to intensify regional and international efforts to overcome terrorism and violent extremism, while reaffirming that "terrorism constitutes one of the most serious threats to international peace and security".
ISIS claimed responsibility for the terror attacks that ripped through the departure area of the international airport and a subway station in the busy morning hours in the Belgian capital and home to the headquarters of the European Union.
The Council "stressed the need to take measures to prevent and suppress the financing of terrorism, terrorist organisations and individual terrorists" in accordance with UNSC resolutions and underlined the need to bring perpetrators, organisers, financiers and sponsors of these reprehensible acts of terrorism to justice.
"The members of the Security Council reiterated that any acts of terrorism are criminal and unjustifiable, regardless of their motivation, wherever, whenever and by whomsoever committed," it said.
