The leaders of the world's 20 most powerful countries have agreed to step up border controls and aviation security in the wake of the Paris attacks that killed 129 people, according to a draft statement. The heads of the Group of 20 (G20) largest economies, meeting in Turkey, condemned the attacks claimed by the Daesh (the so-called IS) terrorist group as "heinous" and said they remained united in fighting terrorism, according to the draft document. The leaders of the world's 20 largest economies also pledged to use all policy tools to address uneven economic growth that falls short of expectations, according to the draft communique. As the G20 leaders gather in Turkey for a two-day meeting on how to boost global growth, much of the economic discussions has been overshadowed by the deadly attacks claimed by Daesh in Paris on Friday that left more than 120 people dead. In a nod to jittery financial markets, the leaders highlighted the need to "carefully calibrate" and clearly communicate policy decisions, according to the draft, the final version of which is due to be released on Monday. They also noted the scale of the refugee crisis, saying all states need to share the burden, including through refugee resettlement and other forms of humanitarian aid, while underscoring the importance of a political solution. They also endorsed the so-called "BEPS" measures to overhaul the global tax system. The draft also calls for stepping up financing for international organizations dealing with migrants, as requested by Europe, and to address the root causes of migrant displacement, such as the war in Syria. The draft calls migration a global problem that must be addressed in a coordinated way. All countries have been urged to help manage the migrant crisis, which is expected to bring a million people from the Middle East and Africa to Europe this year alone, through accepting refugees and humanitarian aid. "We call upon all states to contribute to responding to this crisis, and share in the burdens associated with it, including through refugee resettlement, other forms of humanitarian admission, humanitarian aid and efforts to ensure that refugees can access services, education and livelihood opportunities," the draft said. The draft has yet to be accepted by all and is to be published on Monday. — Agencies
