Explosions struck a natural gas pipeline in Iran early Wednesday, with an official blaming the blasts on a “sabotage and terrorist action” in the country as tensions remain high in the Middle East amid Israel’s war on Hamas in the Gaza Strip.

The blasts hit a natural gas pipeline running from Iran’s western Chaharmahal and Bakhtiari province up north to cities on the Caspian Sea. The roughly 1,270-km pipeline begins in Asaluyeh. Saeed Aghli—manager of Iran’s gas network control center— said the blasts were caused due to “sabotage and terrorism”.
