A large amount of cleaning supplies were sent to the Saudi consulate in Istanbul on Monday, media sources said.

This comes almost two weeks after the disappearance of Saudi journalist Jamal Khashoggi after entering his consulate in Istanbul.

The Anatolia news agency reported that dozens of journalists and media representatives were still waiting in the vicinity of the consulate in the hope of the emergence of new information regarding the fate of Khashoggi.

Journalists in the area noticed that the consulate staff brought large amounts of cleaning supplies they had loaded onto a handcart during the afternoon.

Earlier in the day, Turkish diplomatic sources announced that a joint inspection was scheduled for Saturday evening at the Saudi consulate in Istanbul as part of ongoing investigations into the fate of Khashoggi.

Luminol
A few days ago, Turkish newspapers reported that the investigation team would use chemical luminol during the search for traces of Khashoggi inside the consulate.

Luminol is used in the field of forensic medicine and criminology to detect the effects of light, invisible blood to the public.

This phosphoric coating shows the blood stains removed from the crime scene by the chemical interaction between phosphoric coatings, hemoglobin and oxygen carrying protein to the blood. The appearance of the spots appears after the addition of the paint in the form of a glowing light.

The traces of the Saudi journalist disappeared on October 2 after entering the consulate, prompting the Turkish authorities to launch a thorough investigation into the incident.

Turkish President Recep Tayyip Erdogan called on Riyadh to prove Khashoggi's exit from the consulate, which Saudi authorities have not yet done.

The Washington Post reported that Turkish officials had told their American counterparts that they had audio and video recordings showing the death of Saudi journalist Jamal Khashoggi, which Riyadh denies.

A number of Western countries - led by the United States, Britain and the European Union - have asked Riyadh to reveal the fate of Khashoggi after entering its consulate in Istanbul.
