United Nations (AP) - The U.N. education agency says that 67 million children are not attending school, including 28 million caught in armed conflicts.
UNESCO's 2011 Global Monitoring Report released Tuesday concluded that the world is not on track to achieve the 2015 U.N. target for ensuring universal primary education.
From 1999 to 2008, UNESCO said an additional 52 million children enrolled in primary school -- but it said the number of children out school is falling too slowly.
"If current trends continue," the report warned, "there could be more children out of school in 2015 than there are today."
The report calls for tougher action against human rights violations, an overhaul of global aid priorities and strengthened rights for displaced people.
