US President Donald Trump on Friday called Saudi Arabia's announcement that suspects are in custody in the death of journalist Jamal Khashoggi a "good first step" and said he would work with Congress on a US response.

The president spoke to the media at a defense roundtable in Arizona hours after Saudi Arabia claimed that Khashoggi, a Washington Post contributor last seen on Oct. 2, was killed in a "fistfight" at the Saudi consulate in Istanbul. The kingdom also said that 18 suspects were in custody and that intelligence officials had been fired.

Asked by a reporter whether he thought Saudi Arabia's explanation for Khashoggi's death was credible, Trump said, "I do. I do." But he said before he decided what to do next, he wanted to talk to Saudi Crown Prince Mohammed bin Salman.

"Saudi Arabia has been a great ally, but what happened is unacceptable," Trump said. Regarding the Saudi arrests, he said, "It's a big first step. It's only a first step, but it's a big first step."
