1. Saudi Arabia confirmed that the dissident journalist Jamal Khashoggi was dead, saying he was killed in a fistfight inside the Saudi consulate in Istanbul. It said 18 Saudis had been arrested, but none were identified. Above, Mr. Khashoggi in 2015.

Earlier, Turkish investigators were combing a forest and other sites, an official told us, looking for Mr. Khashoggi’s remains or other clues. Turkish officials have said the dissident journalist was tortured, killed and dismembered by a hit squad.

Turkey’s calculated strategy in leaking information about the case to the news media has been highly effective, keeping the investigation in the headlines and pushing the U.S. to pressure Saudi Arabia.
