ISIS circulated this and the following images appearing to show the destruction of the temple. Here militants appear to be carrying explosives into the temple.

Explosives are seen wired on the exterior of the 2,000-year-old temple.

UNESCO, which had listed the site as one of the most important cultural centers of the ancient world, described the attack on the ancient ruins as a "war crime."
