A 2,000-year-old arch in the ancient Syrian city of Palmyra is the latest casualty by ISIS militants.<br />Professor Maamoun Abduilkarim, the country's director of antiquities, confirmed that ISIS Sunday blew up the Arch of Triumph, one of the city's most recognizable sites.<br />"Shocked" and "shameful," he told ABC News, noting that unlike the two temples that were destroyed earlier this year, the arch has no religious significance.<br />The arch was known to locals as the "Bridge of the Desert" because it linked the Roman Empire to Persia and the East.<br />Professor Abduilkarim said he had not seen photos or videos of the devastation, but learned reports from eyewitnesses.<br />"They're destroying building by building," he said, "within three to six months, at this pace, we're going to lose Palmyra."
