An off-duty police officer, Mevlut Mert Altintas, fatally shot Russian Ambassador Andrei Karlov at a photo exhibition in the Turkish capital on Dec. 19, 2016. Other officers later shot and killed the gunman at the scene.

ANKARA, Turkey (AP) — Turkey's state-run news agency says a prosecutor has concluded that a network led by a U.S.-based Muslim cleric is behind the 2016 killing of Russia's ambassador to Turkey and is seeking prison terms for the preacher and 27 others.

ATHENS, Greece (AP) — Greek police say the head of the consular section at the Russian Embassy in Athens has been found dead in his apartment, but there are no immediate indications of foul play.

A consular employee found the body of 54-year-old Consul Andrey Malanin at his apartment in the Greek capital on Monday.

Police say a coroner will examine the body, while the police homicide department also is investigating the death due to Malanin's diplomatic status.

WASHINGTON (AP) — Donald Trump hammered rival Hillary Clinton during the presidential campaign for failing to prevent the attack on the U.S. mission in Benghazi, Libya, when she was secretary of state. Soon he'll be the one responsible for protecting America's diplomats, but he's offered little insight into how he'll do that.

MOSCOW (AP) — A U.S.-based Muslim cleric on Thursday condemned the killing of Russia's envoy to Turkey and rejected accusations that his movement was behind the attack.

Ambassador Andrei Karlov was shot dead by an off-duty policeman in front of stunned onlookers at a photo exhibition Monday in the Turkish capital, Ankara. Turkish President Recep Tayyip Erdogan has implicated Fethullah Gulen in the killing, accusing his movement of links to the gunman.

The assassination of Russia's ambassador to Turkey fits into a long tradition of political violence in a country where the fallout from the Syrian war is deepening the chaos.

Turkey's toxic combination of problems includes a Kurdish insurgency at home and state purges following a failed coup attempt in July, meaning the security situation will remain extremely tenuous for a while.

ANKARA, Turkey (AP) — Investigators from Turkey and Russia hunted for clues Tuesday in the assassination of Russia's ambassador to Turkey in front of stunned onlookers at a photo exhibition in Ankara.

A team of 18 Russian investigators and foreign ministry officials arrived in Turkey and began inspecting the art gallery where the shooting of Andrei Karlov took place.

The assassination of Russia's ambassador to Turkey could actually bring the two regional powers closer together, with Russia reaping political benefits by arguing that it has paid a high price for fighting terrorism as Turkey, embarrassed by its security breaches, increasingly coordinates with Russia in neighboring Syria.

The two nations were already trying to resolve their differences over the war in Syria since Turkey shot down a Russian military jet along the Syrian border last year.
