Investigators of the Grand Mosque crane crash have achieved a major breakthrough and those responsible for the incident will be put on trial, local media reported on Sunday.

Among those questioned were engineers and project managers. The engineering department of the General Presidency of the Two Holy Mosques will also have to submit a report on the crane, sources were quoted as saying. The crash, days before the Haj season began this year, claimed 111 lives and injured 238.

The chief prosecutor summoned experienced engineers in the field of urban construction to be familiarized with more details on the crane, its use and the safety measures required.

He is due to prepare the indictment against those found guilty of dereliction of duty and submit it to the specialist court seeking their trial.

The Saudi Binladin Group will be committed to the ruling in this regard, according to the Royal Decree, the sources said.

Custodian of the Two Holy Mosques King Salman ordered massive payouts for the families of those killed and injured in the tragedy.

According to preliminary investigations, the main cause of the crane crash was strong winds and wrong position of the crane.
