The Islamic State (IS) militant group has destroyed part of what's considered the most important temple at the ancient Syrian site of Palmyra, activists and witnesses say.

The extent of the damage to the 2,000-year-old Temple of Bel is not clear but local residents have described being shaken by a large explosion.

The reports come a week after IS blew up another temple at the ancient city.
This is when you want some special force snipers around!
