GENEVA: A global organization dedicated to preventing violent extremism said on Friday the US had made a mistake in withdrawing its support while the risk of militant attacks surges in the Middle East and Africa’s Sahel. The Global Community Engagement and Resilience Fund, which supports prevention programs across dozens of countries with communities vulnerable to extremism — appeared on Wednesday in a White House memo announcing a US pullout from 35 international agencies and 31 UN entities it said rejected US interests.
