At least 16 people were killed and 28 others injured after a bus crashed and overturned along a road connecting two popular tourist towns in Egypt.

The horrific crash happened Wednesday, Sept. 2, on the road between Dahab and Nuweiba in Egypt’s South Sinai Governorate, according to the country’s Ministry of Health.

Health Minister Dr. Khaled Abdel Ghaffar confirmed that 16 people died in the rollover and another 28 passengers were rushed to medical facilities for treatment.

Medical teams were continuing to closely monitor the injured as authorities scrambled to respond to the deadly scene.

Officials said 20 ambulances were dispatched following the crash.

The cause of the wreck remains unclear.

“The ministry confirms that all medical teams are working at full capacity to deal with the incident with utmost efficiency and speed,” the Ministry of Health said in a statement translated from Arabic, adding that the situation was being monitored “moment by moment.”

Officials also offered condolences to the victims’ families and wished those injured a speedy recovery.

The injured were initially taken to the Al-Mazina Family Medicine Center before some were transferred to larger facilities, including Sharm El-Sheikh International Hospital, Al-Fayrouz Medical Complex and Saint Catherine, according to Sky News.

A number of Jordanian citizens were reportedly aboard the bus.

Citing Jordan’s Foreign Ministry, Sky News reported that early information indicated Jordanians were among both the dead and injured.

The crash unfolded in one of Egypt’s best-known vacation regions.

Dahab and Nuweiba are popular destinations for tourists drawn to the Sinai Peninsula’s beaches, snorkeling and world-famous diving in the Red Sea.

Dahab sits about 53 miles north of Sharm El-Sheikh, one of Egypt’s busiest resort destinations.

Sharm El-Sheikh attracts millions of visitors and has long been considered one of the country’s premier vacation spots.

Authorities have not yet disclosed what may have caused the bus to overturn or released additional details about the identities of those killed.
