UK: Allegations on Khashoggi's disappearance 'serious'

British government on Monday said the allegations on the disappearance of Washington Post journalist Jamal Khashoggi are "extremely serious".

"These are extremely serious allegations," said a British Foreign Office representative in a statement.

"We are aware of the latest reports and are working urgently to establish the facts, including with the government of Saudi Arabia," the representative said.

Jamal Khashoggi, journalist and regular columnist for the Washington Post, has been missing since he entered the Saudi consulate in Istanbul on Oct. 2.

Turkish police investigating the case had said in a statement Saturday that 15 Saudis, including several officials, arrived in Istanbul on two planes and entered the consulate while Khashoggi was inside.

The Chief Public Prosecutor’s Office in Istanbul initiated an investigation on the day of the incident while the consulate also said on Twitter that it was working in coordination with Turkish authorities.

Turkey on Monday conveyed its expectation of "full cooperation" from Saudi Arabia in search of the missing Saudi journalist.
