An explosion on the Arab Gas Pipeline that caused a power blackout in Syria on Monday was the result of a “terrorist” attack, state media cited the energy minister as saying.

Ikhbariya TV channel showed footage of a large fire after the explosion, which officials said occurred between the towns of Ad Dumayr and Adra, northwest of the capital of Damascus.

The channel later said the fire had been extinguished.

“Assessments show that the explosion … was the result of a terrorist attack,” state news agency SANA quoted Minister of Petroleum and Mineral Resources Ali Ghanem as saying.

He did not provide further detail.
