President Donald Trump makes an unannounced trip on Wednesday to honour the returning remains of a US Navy Seal killed in a weekend raid in Yemen. Chief petty officer William “Ryan” Owens, a 36-year-old from Peoria, Illinois, was the first known US combat casualty since Trump took office less than two weeks ago. An eight-year-old American girl was among 30 others killed in the operation on an al-Qaida compound. Three other US service members were wounded.
