A massive construction crane crashed into Makkah’s Grand Mosque in stormy weather Friday, killing at least 87 people and injuring 201, Saudi authorities said, less than a fortnight before the hajj pilgrimage starts. The civil defence authority said on Twitter that emergency teams were sent to the scene after a “crane fell at the Grand Mosque.” That came about an hour after it tweeted that Makkah was “witnessing medium to heavy rains,” with some pictures circulating on social media showing lightning. Authorities have not yet released an official account on what happened. Pictures of the incident on Twitter showed bloodied bodies strewn across a courtyard where the top part of the crane, which appeared to have bent or snapped, had crashed into the several storey-high building. The governor of Makkah region, Prince Khaled al-Faisal, has ordered an investigation into the incident and was heading to the mosque, the official @makkahregion page on Twitter said. He added in a subsequent tweet that despite the tragedy, this year’s hajj will go on as per schedule, directing officials concerned to “rearrange” and “restore” the site of the crash. He further said that the Saudi government will provide facilities to the injured to complete their religious obligations. Meanwhile, online activists created a hashtag on Twitter urging Makkah residents to donate blood at hospitals in the area. No details were immediately available on the nationalities of the victims. But Iran’s official IRNA news agency, quoting the head of the Hajj Organisation, said that 15 Iranian pilgrims were among those injured. Most of them were treated as outpatients, Saeid Ohadi said. A massive project is currently underway to expand the area of the mosque by 400,000 square metres (4.3 million square feet), allowing it to accommodate up to 2.2 million people at once. The mosque is surrounded by a number of cranes. The hajj has largely been incident-free during the past few years, with Saudi Arabia investing billions of dollars in transport and other infrastructure to facilitate the movement of the huge numbers of people who take part. The official SPA news agency said in a statement that by Friday, almost 800,000 pilgrims had arrived into the kingdom for hajj. Meanwhile, Pakistan has extended all possible help to the kingdom, directing its ambassador in Riyadh to visit patients in hospitals. Prime Minister Nawaz Sharif also expressed his deep condolences over the unfortunate incident, Radio Pakistan reported. Nearly 100,000 Pakistanis are in Saudi Arabia to perform hajj.
