Saudi Arabia says missing journalist Jamal Khashoggi died

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, reported Arab News.

Trump said “Saudi Arabia has been a great ally, but what happened is unacceptable,” 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.”

Saudi Arabia announced on Saturday the death of missing journalist Jamal Khashoggi, saying a preliminary investigation indicated he lost his life after a fight at the Saudi consulate in Istanbul.

“The discussions between Jamal Khashoggi and those he met at the kingdom's consulate in Istanbul... devolved into a fistfight, leading to his death,” the Saudi Press Agency said, citing the public prosecutor.

Eighteen Saudis have been arrested in connection with the incident and the investigation is ongoing, the public prosecutor said.

Acording to statement on the SPA,  “The Kingdom expresses its deep regret at the painful developments that have taken place and stresses the commitment of the authorities in the Kingdom to bring the facts to the public opinion, to hold all those involved accountable and bring them to justice.”

Khashoggi, a Saudi journalist who lived in the US, disappeared on Oct. 2 after visiting the consulate to complete paperwork related to his divorce.

Deputy intelligence chief Ahmed Al-Asiri was removed from his position and Saud Al-Qahtani from his advisory role at the Royal Court, through royal decrees.

Three other intelligence officials who were also sacked have been named as Mohammad bin Saleh Al-Rumaih, Abdullah bin Khalifa Al-Shaya and Rashad bin Hamed Al-Muhamadi.

King Salman also ordered the creation of a ministerial committee, headed by Saudi Crown Prince Mohammed bin Salman, to restructure the country’s General Intelligence agency and issue the results of its work within a month.

Members of the committee include the interior and foreign ministers as well as the heads of the General Intelligence and State Security.

A team of Saudi investigators were sent to Istanbul and have been working on the case with Turkish detectives, who entered the consulate on Thursday.

Earlier in the week, Saudi Arabia promised a thorough and transparent investigation into what happened to the journalist in Turkey.
