Washington, Feb 2 (IANS): US President Donald Trump made an unannounced visit to the Dover Air Force Base to honour a US service member killed in a raid in Yemen, the media reported.

Chief Petty Officer William Owens, a Navy SEAL (sea, air, and land), died of wounds suffered during a raid on Sunday in Yemen against the Al Qaeda, according to US Central Command.

Trump went to base in Delaware, along with his daughter, Ivanka, and state Senator Chris Coons, to partake in the dignified transfer ceremony to honour Owens, CNN reported.

Trump later described the ceremony as "very sad, very beautiful", in remarks at a White House swearing-in of Secretary of State Rex Tillerson.

Trump spoke over the weekend with Owens' wife and offered his condolences to his father and three children.

Owens was the only US service member to die on Sunday's operation, which killed an estimated 14 Al Qaeda militants including three senior leaders, military sources told CNN.

The raid also resulted in the death of the 8-year-old daughter of former Al Qaeda leader Anwar Al-Awlaki, a US citizen who was killed in a drone strike in 2011.

The raid yielded what White House press secretary Sean Spicer described on Wednesday as a "an unbelievable amount of intelligence that will prevent the potential deaths or attacks on American soil."
