Syrian regime army General Suheil Al-Hassan has threatened civilians in Eastern Ghouta with more "hell".
"No one will come to your aid. And if you seek refuge, you will be rescued with water like molten brass," Al-Hassan said in a video circulated on YouTube.
Al-Hassan and his elite Tiger Forces arrived last week to join the Syrian army's attack against the last opposition stronghold.
This is not the first time a Syrian regime army officer publicly threatens civilians. In September, a Syrian officer threatened refugees with death if they returned to the country.
Al-Hassan is known for his use of aerial bombardments before any ground attack, this has led to the death of tens of thousands of people and the injury of many more.
He received an honour from the Russian Ministry of Defence in August last year for his "sacrifices".
The Syrian regime forces began on Sunday night bombing Eastern Ghouta while beefing up military reinforcements in the area ahead of a possible attack.
The French news agency reported that the number of victims, since Sunday has increased to more than 330 people, including about 70 children and more than 1,500 injuries.
