TEHRAN, Young Journalists Club (YJC) - According to a White House statement on Tuesday, Trump and May "agreed not to allow the use of chemical weapons to continue.” May spoke with Trump by telephone agreeing that the reported attack was "utterly reprehensible."
"They agreed they would continue working closely together and with international partners to ensure that those responsible were held to account," a statement from May's office said.
An alleged chemical attack on Saturday in the militant-held town of Douma in the Eastern Ghouta region left dozens dead and drew international condemnation from various countries and international bodies.
May had earlier agreed the same thing in a call with French President Emmanuel Macron.
Former British Prime Minister Tony Blair had also said that Britain should support a military action against Syrian President Bashar al-Assad in response to the recent alleged chemical weapons attack in Syria.
The US and its allies have been bombarding what they call Daesh positions inside Syria since September 2014 without any authorization from the Damascus government or a UN mandate.
The strikes have on many occasions resulted in civilian casualties and failed to fulfill their declared aim of countering terrorism.
When asked whether Britain would join the United States if Washington decided on further military action in Syria, she declined to answer the question directly.
"We believe that those responsible should be held to account," she told reporters in Cambridgeshire.
With less than a year to go until Brexit, May seeks to deepen its so-called "special relationship" with the United States with a wide-ranging free trade deal that would help cushion the impact of leaving the European Union (EU).
Britain reportedly provided over 1,400 military personnel to the so-called US-led coalition against Daesh.
