The head of the World Health Organization, Tedros Adhanom Ghebreyesus speaks during a media conference at an EU Africa summit in Brussels on Feb. 18, 2022.
Tedros "arrived at Aleppo airport to tour some hospitals and shelters with (Syria's) health minister and the governor of Aleppo", the official news agency SANA said.
His visit came five days after a devastating 7.8-magnitude earthquake rocked Turkey and Syria, killing more than 24,000 people including at least 3,553 in war-torn Syria alone.
Upon his arrival, Tedros said he was accompanying "emergency medical supplies of around 37 metric tonnes".
"We are very happy that we could come with the supplies," he told reporters at Aleppo airport.
"This is the first supply we are sending."
He added that the WHO would continue to provide emergency medical services and bring in more emergency supplies necessary for "trauma management".
"Tomorrow, there will be another round with more than 30 metric tonnes," he said.
He expressed concern over the after-effects of the earthquake, especially the disruption of services.
"People are exposed to diarrhoeal diseases... and other health problems especially mental health problems," he said.
"We will work together to address the impact of the earthquake, not only the emergency services during the earthquake.
Since Monday's earthquake, rescuers and volunteers have been scrambling with little means to find survivors under concrete debris of collapsed buildings.
