Washington reveals the number of its troops in Iraq, Syria and Afghanistan
The Pentagon announced that more than 500 people were deployed in Syrian territory.
"The number of our troops in Afghanistan is about 14,000, with about 503 operating in Syria and 5262 in Iraq," said Kenneth McKinsey, director of the US Joint Chiefs of Staff, during a briefing at the Pentagon.
Since June, the United States has been leading an international coalition against the terrorist organization Daqash, which has been waging a campaign of "firm resolve" against insurgents in Iraq and Syria.
Coalition forces operate in Iraqi territory with official invitation and approval from the Iraqi government, but their operations in Syria come without the approval of the country's authorities, which accuse the United States and its allies of perpetrating massacres of innocent civilians through indiscriminate air raids and providing support to terrorist groups.
The United States officially says its military action in Syria is limited to training and supporting local opposition forces without direct involvement in hostilities.
