One person was injured in central Athens Wednesday after a pre-dawn explosion sparked a fire and damaged a vacant building.
The man, 78, is said to be in serious condition with burns to his arms and legs.
The powerful blast, which took place at 6.45 a.m. at an office block currently under renovation on Syngrou Avenue near the Temple of Olympian Zeus, damaged several nearby storefronts.
Police shut down traffic in the area.
The cause of the blast remains under investigation.
“We don’t know what caused it yet, there is extended material damage, and a fire started,” a fire brigade official told Skai TV.
