Damascus, Dec 30
The death toll from a powerful explosion at a Syrian weapons depot near the Adra Industrial City in rural Damascus rose to 11, with most of the casualties believed to be civilians, a war monitor reported.
According to the Syrian Observatory for Human Rights and local media, search and rescue teams remain at the scene to recover bodies and clear debris.
The blast sent debris flying and caused extensive damage to the facility associated with the now-ousted Bashar al-Assad's government, news agency reported.
Initial reports indicated at least two people were killed, but the death toll continued to rise throughout the day.
A video posted online showed significant destruction and multiple fatalities.
Guterres underscored that Israel and Syria must uphold the terms of the 1974 Disengagement of Forces Agreement, which remains fully in force.
