Syria has declared the UK's ambassador persona non grata in a symbolic rebuke.
Simon Collis, who left the troubled country in March, and the US, French and Turkish representatives were among those told they are no longer welcome.
The move by Bashar Assad's regime comes after the countries expelled more than a dozen senior Syrian diplomats in protest at the massacre of scores of people in the Houla area of Homs.
A Foreign Office spokeswoman said: "We announced the expulsion of Syria's charge d'affaires - Syria's most senior diplomat in the United Kingdom - and two other diplomats from the embassy on May 29.
"The action was a direct response to the horrific killing of over 100 people including 49 children and 34 women in Houla.
"The UK has taken this action in concert with partners across the world sending a stark signal to president Assad and those around him that their actions have consequences and that they cannot act with impunity.
"It was also an expression of the international outrage at the Syrian regime's repression of its people, which continues even after the international community and United Nations Security Council's condemnation.
"The Syrian government's decision today appears to be a reciprocal gesture.
"The UK Government has already withdrawn all diplomatic staff from Syria on March 1, 2012."
The news came after reports rebel forces killed 80 Syrian soldiers over the weekend.

Russia says international envoy Kofi Annan will visit Moscow on Monday to discuss the ongoing crisis in Syria. Russia also called for an inquiry into an alleged massacre that took place in the village of Tramseh on Thursday. "We have no doubt that this wrongdoing serves the interests of those powers that are not seeking peace but persistently seek to sow the seeds of interconfessional and civilian conflict on Syrian soil," Russia's foreign ministry said in a statement, according to Reuters. Moscow did not apportion blame for the killings.

The Associated Press obtained a video that purports to show the aftermath of an alleged massacre in the village of Tramseh, near Hama.
How do Syria's fighters get their arms? An overview put together by Reuters explains that there are three gateways to the country -- Lebanon, Turkey, and Iraq.
Syrian rebels are smuggling small arms into Syria through a network of land and sea routes involving cargo ships and trucks moving through Turkey, Lebanon and Iraq, maritime intelligence and Free Syrian Army (FSA) officers say. Western and regional powers deny any suggestion they are involved in gun running. Their interest in the sensitive border region lies rather in screening to ensure powerful weapons such as surface to air missiles do not find their way to Islamist or other militants.

According to the Hama Revolutionary Council, a Syrian opposition group, more than 220 people have been killed in a new alleged massacre in Taramseh. Earlier reports said more than 100 people were killed. "More than 220 people fell today in Taramseh," the Council said in a statement. "They died from bombardment by tanks and helicopters, artillery shelling and summary executions."
Fadi Sameh, an opposition activist from Taramseh, told Reuters he had left the town before the reported massacre but was in touch with residents. "It appears that Alawite militiamen from surrounding villages descended on Taramseh after its rebel defenders pulled out, and started killing the people. Whole houses have been destroyed and burned from the shelling," Sameh claimed.
