Rami Abdel Rahman, the founder the Syrian Observatory for Human Rights, spoke out against, what he called, the hypocrisy of the international community in focusing on chemical weapons and overlooking the "endless bloodbath" in Syria.
Day after day, from a base in the drab central English city of Coventry, the exiled Rahman and his volunteers have counted the human toll of Syria's civil war ever since the conflict erupted in March 2011.
"In Syria, out of more than 120,000 people killed, 500 were killed with chemical weapons. Are these more horrendous deaths than the others?" Rahman told AFP news agency in London.
"Nothing has changed at all. The clashes continue. Blood continues to be spilled and the intensity of the conflict increases," said the 40-year old, through an Arabic translator.
"With the focus on chemical weapons, we forget about the daily deaths of the Syrian people by shelling, tank fire, gunfire, car bombs, mortars falling on civilian areas."
Rahman says that according to his figures the conflict is still killing 4,000 to 5,000 people a month, from soldiers, pro-government militia and Lebanese Hezbollah fighters to rebels, and civilians.
"The regime commits dozens of atrocities every day," says Rahman, but he adds that the other side is also responsible for war crimes, as Al-Qaeda-affiliated groups such as the Islamic State of Iraq and the Levant (ISIL) and the al-Nusra front try to establish an "alternative dictatorship"
