The Group of 20 leading economies (G20) said on Monday the rise in terrorism undermined international peace and security and endangered efforts to strengthen the global economy.
In a statement issued after a meeting in the sea resort of Belek in the Antalya province of Turkey, the leaders of the world's 20 biggest economies stressed, however, that terrorism should not be associated with any religion, nationality or ethnic group.
The statement, confirming a draft seen by Reuters on Sunday, said the G20 would work together to suppress and prevent terrorist acts and cut off financing for those who commit them.
The 20 leading countries also pledged to exchange operational information and tighten border controls as well as global aviation security.
Leaders of the world's top 20 economies also urged all nations to respond to a worldwide refugee crisis.
"We call upon all states to contribute to responding to this crisis, and share in the burdens associated with it," they said in a final communique.
