The Group of seven industrialised nations (G7) Foreign Ministers, are working towards a common position on the Syrian conflict, before the U.S. Secretary of State, Mr Rex Tillerson, flies to Russia to persuade Moscow to abandon its Syrian ally.
Mr Tillerson is also scheduled to meet officials from the allied Middle Eastern countries before heading to Moscow.
The U.K has suggested threatening tightly-focused sanctions on Russian and Syrian military officers following the latest apparent use of chemical weapons in Syria.
Syria however, denies it carried out the chemical attack on the rebel-held town of khan Sheikhoun that left 89 people dead last week.
In response to the attack, the U.S said it destroyed a fifth of the Syrian operational aircraft in an air strike on the Shayrat airbase.
