ISTANBUL (Reuters) - Turkish President Tayyip Erdogan shared details of the case of slain Saudi journalist Jamal Khashoggi in bilateral talks during a four-way summit with the leaders of Russia, France and Germany, he said on Saturday.

Erdogan, speaking at a joint news conference following a summit in Istanbul, said Saudi Arabia needed to say who sent to Turkey the 18 people believed to be responsible for Khashoggi’s killing. He also said Turkey valued the conclusion of discussions between Turkish and Saudi prosecutors, who are due to meet on Sunday.
