US-based Saudi journalist Jamal Khashoggi, a well-known critic of Saudi Arabia and its leadership, went missing in Turkey on October 2.
US and Turkish officials have now been quoted saying they have proof that he was killed inside the Saudi consulate in Istanbul.

Diplomatic pressure is also increasing and global businesses are reassessing their ties and pulling out of deals with the kingdom.
