Roman-era monument destroyed by IS terrorists
Islamic State militants have destroyed a landmark monument and parts of a second century theatre in Syria.
The group attacked Palmyra's Roman-era Tetrapylon and an amphitheatre, the Syrian government and opposition said.
The UN condemned the incident as a war crime.
A Syrian government official said he feared for the remaining antiquities in Palmyra, which the extremist movement recaptured last month.
The area, a Unesco world heritage site that once linked Persia, India and China with the Roman Empire and the Mediterranean area, has already seen destruction at the hands of IS.
The town first fell to militants in May 2015, when they held it for 10 months. During that time, IS damaged a number of relics and eventually emptied the area of most of its residents, causing an international outcry.
Palmyra fell again to the group last month, nine months after a Syrian government offensive was hailed as a victory for Damascus.
