There's only one thought that comes to Rami al-Sayed's mind when asked to describe an ongoing Syrian government offensive against an ISIL pocket south of the capital, Damascus.
"Doomsday," says the 35-year-old. "It's like Judgement Day."
Al-Sayed is a former resident ofHajar al-Aswad, one of the neighbourhoods of the besieged Palestinian refugee camp of Yarmouk which is currently under attack by forces loyal to Syrian President Bashar al-Assad and Russian fighter jets.
