PARIS (AP) — As Islamic State extremists recapture the ancient Syrian city of Palmyra, the French president and the UNESCO chief are inaugurating an exhibit in Paris to educate the public about the wonders of endangered UNESCO heritage sites in Palmyra and the Middle East.

The show that opens Wednesday in collaboration with the Louvre plunges visitors into a three-dimensional projection featuring never-before-seen images of Palmyra taken by a drone in April after the city was liberated from Islamic State fighters.

Although militants destroyed two sacred temples in Palmyra, researcher Yves Ubelmann says the Paris exhibit uncovers how much of Palmyra remains intact — "for how much longer isn't known."

Ubelmann said he was "scared... about the arrival of Islamic State, because we don't know what they'll destroy."
