A US military air strike in
north-western Syria has killed more than 100 al-Qaeda militants at a
training camp, the Pentagon says.
The strike on Thursday was the second major US military attack in the final hours of Barack Obama's presidency.
Less than 24 hours earlier, a combination of B-2 stealth bombers and drones killed up to 90 so-called Islamic State (IS) militants in two camps in a remote area of Libya, officials said.
Capt Davis said the Syria attack disrupted training operations "and discourages hard-line Islamist and Syrian opposition groups from joining or co-operating with al-Qaeda on the battlefield".
He said it capped a series of successful strikes against al-Qaeda recently. "These strikes, conducted in quick succession, degrade al-Qaeda's capabilities, weaken their resolve, and cause confusion in their ranks," he said.
