The World Health Organization (WHO) said it has suspended operations at its global emergency logistics hub in Dubai due to the ongoing conflict in the Middle East, BBC News reports.

WHO Director-General Tedros Adhanom Ghebreyesus said at a press conference that operations at the facility are currently suspended due to security concerns.

According to WHO Regional Director for the Eastern Mediterranean Hanan Balkhy, the hub processed more than 500 emergency orders for 75 countries around the world last year.

The WHO said the hub’s work has been “temporarily suspended due to the unsafe situation, the closure of airspace, and restrictions affecting access to the Strait of Hormuz.”
