Gen. Martin Dempsey, chairman of the U.S. Joint Chiefs of Staff, recommended this week the U.S. government send training teams to Iraq and speed up arms sales to strengthen Iraq's military, The Independent said.
"We welcome this kind of co-operation and we consider it a part of the existing agreement between us," a spokesman for Iraqi Prime Minister Nouri al-Maliki said. "Because of the high risks the region faces, I think there should be bigger co-operation and co-ordination between all countries threatened by terrorism."
