In Turkey, police have arrested at least 13 people following the assassination of Russia’s ambassador to Turkey, Andrey Karlov, by an off-duty Turkish police officer in Ankara Monday. Among those arrested were the shooter’s mother, father, sister and other family members. The owner of an apartment where the shooter once lived was also arrested. On Tuesday, Turkish authorities increasingly pinned the blame for the assassination on people loyal to exiled Turkish cleric Fethullah Gülen, who lives in the United States in the Poconos. Gülen called the accusations “laughable.” This is U.S. State Department spokesperson John Kirby speaking Tuesday about Secretary of State John Kerry’s meeting with Turkey’s foreign minister.

John Kirby: “The secretary, in his conversation with the foreign minister, did raise his concerns about some of the rhetoric coming out of Turkey with respect to American involvement-slash-support, tacit or otherwise, for this unspeakable assassination yesterday, because of the presence of Mr. Gülen here in the United States. And it is a—it’s a ludicrous claim, absolutely false. There’s no basis of truth in it whatsoever. And the secretary made that very clear in his discussions today with the foreign minister.”
