Syria's top diplomat in London resigned Monday (July 30th) saying he could no longer able to represent the regime, AFP reported.

The move comes after a series of defections by senior Syrian officials in recent weeks, including diplomats in several countries and top army officers.

The British Foreign Office said in a statement that charge d'affaires Khaled al-Ayoubi said Monday that "he is no longer willing to represent a regime that has committed such violent and oppressive acts against its own people, and is therefore unable to continue in his position".

Britain expelled the previous Syrian charge d'affaires, Ghassan Dalla, and two other diplomats in May, and Syria had earlier withdrawn its ambassador from London.

"Mr. al-Ayoubi was the most senior Syrian diplomat serving in London. His departure is another blow to the Assad regime," the Foreign Office said.

Meanwhile, the Armenian Foreign Ministry referenced a diplomatic note from the Syrian embassy in Armenia that the Syrian consul in the country, Mohammad Hussam Hafez, "has left his post", without providing further details.
