A fire, which occurred at the ammunition depot in the Turkish province of Kilis near the border with Syria on Thursday, left at least 10 servicemen injured, local media reported.
Explosions triggered by the fire initially prevented firefighters from extinguishing the flames, the Daily Sabah newspaper reported.
Ambulances, search and rescue teams are on the site. The reason behind the fire is being investigated.
Russia and Turkey along with Iran are guarantors of the Syrian ceasefire regime that came into force in late December. The guarantors also play an active role in the Astana peace process seeking to reach the national reconciliation in Syria.
