UK Prime Minister David Cameron and US President Barack Obama agreed that the settlement of the Syrian crisis must involve Russia and Iran, Downing street said in a Sunday statement.

MOSCOW (Sputnik) � The two leaders held a telephone conversation on a range of issues on Friday, the statement said.

"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," the statement read.

Cameron told Obama that the UK was ready to do more to help the Washington-led coalition counter Daesh (also known as Islamic State or 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.
