(CNN) – The iconic columns of a temple with historic significance in Palmyra, Syria, are still standing despite an explosion there Sunday, the antiquities chief in Syria, Maamoun Abdulkarim, said Monday.

He said there was an explosion Sunday inside the walls of the Temple of Bel, and while the extent of the damage is not yet known, witnesses report the walls are still standing. He called the site “the most important temple in Syria and of the most important in the whole Middle East.”

For nearly 2,000 years — back to the days when Christ walked the earth — the Temple of Bel has been the center of religious life in the Syrian city of Palmyra.

But now, at least part of the most historically significant temple in Palmyra has been destroyed by ISIS, according to the UK-based Syrian Observatory for Human Rights, which relies on a network of activists in Syria for information.
