London said on Sunday that US President Barack Obama and the British Prime Minister David Cameron had agreed in a phone conversation that the political settlement of the Syrian crisis must involve Russia and Iran.
Downing Street announced in a statement that the phone call between Obama and Cameron had been made on this past Friday. This was part of a series of issues that the two discussed, the statement added.
"The Prime Minister and the President agreed on the need for progress on the political track and the importance of engaging with Russia and Iran as part of this," Russia’s Sputnik news agency quoted the statement of Downing Street as saying.
Cameron told Obama that the UK was ready to do more to help the Washington-led coalition counter “Daesh” (also known as ISIL).
"The Prime Minister explained we were increasing the number of Tornado aircraft deployed in the region and sending a new squadron of Typhoon to strike Daesh targets inside Syria. We stood ready to do more to support the global coalition campaign against Daesh," the statement read.
According to Downing Street, Obama congratulated Cameron on expanding the anti-terrorist aerial campaign to Syria, "noting the UK would play an important part in ensuring the ultimate defeat of Daesh."
London launched its first strikes in Syria on Thursday and Saturday, after the country’s lawmakers approved the military campaign on Wednesday.
The United Kingdom has been conducting airstrikes on Daesh positions in Iraq since September 2014, as part of a US-led international coalition against the extremist group.
