Great Britain has reportedly expelled Syrian representatives in response to the massacre in Houla, dpa reported.
Last week a massacre in central town of Houla left at least 108 people dead, including 49 children. Many others were left wounded.
Diplomatic sources said on Tuesday that Spain and Germany will also expel Syrian ambassadors from those countries due to the Houla massacre.
In case with Germany, Syrian Ambassador Radwan Lutfi had been summoned to the Foreign Ministry, and he has some 72 hours to leave the country.
Syria has been covered by anti-government speeches for more than a year resulting in violent clashes. According to UN figures, the total number of victims in the country exceeds 10,000.
In turn, the Syrian authorities say the number of those killed in clashes was over 2000 soldiers and police officers against whom there are well-armed militants.
