Looks like it was a big-scale op:

- officially: U.S. Forces Kill 14 Al-Qaida in the Arabian Peninsula Terrorists in Yemen.

- unofficially: US Special Operations air and ground assault takes out al Qaeda compound in Yemen - and Trump doesn't care about 'collateral damage'.

Large scale US Special Operations assault in Yemen leaves 1 US Navy SEAL dead, 3 Special Operations members wounded, upwards of 45 al Qaeda members dead, and 16 civilians killed.
(Graffic images!!!)

Not sure Yemenis are going to take this lightly (and they are the way to go when dealing with the AQAP in Yemen). AQAP, of course, even less so, especially since Awlaki's daughter was killed too (apparently by a bullet...): Commando dies in U.S. raid in Yemen, first military op OK'd by Trump
Eight-year old Anwar al-Awlaki [sic] - the daughter of U.S.-born Yemeni preacher and al Qaeda ideologue Anwar al-Awlaki, who was killed in a U.S. drone strike in 2011 - was among the children who died in the raid, according to her grandfather.
"She was hit with a bullet in her neck and suffered for two hours. Why kill children? This is the new administration - it's very sad, a big crime," Nasser al-Awlaki told Reuters.
To make sure: I'm anything but a 'fan' of Awlaki... but executing children by head-shots... well, is at least likely to have insta-created about 50-100 new terrorists.
