The US sought to unite nations around a common vision for combating violent extremist groups in three days of talks which ended Thursday long on words but short on concrete steps.
In the wake of shocking beheading and murder by Daesh group, as well as a series of lone attacks in European cities, governments must remain "unwavering in our fight against terrorist organizations," US President Barack Obama said.
He vowed to ministers from some 60 nations to continue to hunt down Al-Qaeda militants in places like Yemen and Somalia and to help shore up fragile nations to "prevent ungoverned spaces where terrorists find safe haven."
On the final day of his high-profile summit, Obama laid out some priorities to neutralize the "warped ideologies" espoused by extremist groups like Daesh.
In a statement released at the end of the talks, the participants promised to "chart a path for progress" ahead of summit talks on the margins of the UN General Assembly in September.
Condemning the recent wave of attacks, the statement "underscored" a commitment to fighting extremist groups and highlighted the need to support local religious and community leaders.
