After a day of marathon talks in Geneva, US Secretary of State John Kerry and Russia's Foreign Minister Sergei Lavrov announced the truce, which is set to come into force on Monday (local time), the first day of the Muslim holiday of Eid.

Mr Kerry said he believed the plan would lead to talks to "stop the conflict" which has raged for more than five years, killing more than 290,000 people and displacing millions.

He called on "every Syrian stakeholder" to support the plan to "bring this catastrophic conflict to the quickest possible end through a political process".

US officials described the intercept by the SU-27 jet on Wednesday as "dangerous and unprofessional".

Russia's defence ministry said the US plane had been approaching Russian territory and the SU-27 pilots had adhered to international rules.

Russia is currently carrying out military exercises in the Black Sea.

Pentagon spokesman Capt Jeff Davis said the US Navy P-8A Poseidon aircraft had been conducting routine operations in international airspace when the Russian fighter made the unsafe manoeuvre.

Mr Erdogan said US counterpart Barack Obama floated the idea of joint action against the militants when they met at the G20 summit in China.

He said Turkey would have "no problem" with such action.

Last month Turkey launched an operation inside Syria, targeting both IS and Kurdish rebels.

Turkish-backed militia drove IS from the border town of Jarablus, but Turkey has also been concerned with checking the advance of Kurdish forces whom it regards as terrorists.

With regional tensions rising over China's aggression in the disputed waterway, the Assistant Chief of Staff to the US Army, Tom Hanson, also suggested Australia will need to make a choice between its long-standing alliance with the United States and economic relationship with Beijing.

"It's very difficult to walk this fine line between balancing the alliance with the United States and the economic engagement with China," he told Radio National.

It's a storyline that's telling about Australia's attitude to Asia's pre-eminent power. On the one hand, China is the country's biggest trading partner, but it also poses a potential regional military threat that's drawing the attention of the US, Australia's closest defence ally.

China, for its part, appears keenly aware of Australia's apparent reluctance to embrace it fully. In recent months, a series of bilateral irritations have sent relations between the two countries plunging to their lowest point for nearly a decade.

Clashes in places where so-called Islamic State (IS) was not present were a "source of deep concern", the US envoy to the anti-IS coalition tweeted.

Turkish forces have attacked what they say are Kurdish "terrorists" since crossing the border last week.

But the Kurdish YPG militia says Turkey just wants to occupy Syrian territory.

Spokesman John Kirby maintained the payment was negotiated separately from the release, but said it was withheld until the Americans had left Iran.

Five Americans held in Iran were released in January in exchange for seven detained Iranians.

The US airlifted $400m (£300.8m) worth of cash to Iran on the same day.

The exchange came as the US lifted international sanctions against Iran as part of the country's historic nuclear deal.

The timing of both incidents has prompted an outcry from Republicans, who accused the Obama administration of quid pro quo.

"The Government has the duty to take the necessary measures seeking compensation for material and moral damages caused by the United States" to the country and Iranians over the past 63 years, the text reads.

It cites "material or moral damage" caused by the US during the coup against nationalist leader Mohammad Mossadegh in 1953, in the Iran-Iraq war between 1980 and 1988, in the destruction of oil platforms in the Gulf and in espionage against the Islamic republic.

China has developed a growing influence in the Pacific over recent years and this month Russia sent nearly US$9 million worth of weapons to Fiji with the negotiations for a second shipment underway.

However the US Assistant Secretary of State for East Asian and Pacific Affairs, Daniel Russel, said all countries could operate in the region effectively.

Noel Santillan had planned to drive from Keflavik International Airport to a hotel in central Reykjavik – but a spelling mistake sent him six hours away to a remote fishing town in Siglufjorour, North Iceland, reported theIceland Monitor.

A Siglufjorour resident who answered the door at midday was astonished when a weary-looking Santillan held out a piece of paper and politely enquired if he was at the right address.
