Ahmed Abu Khawla told Reuters on Saturday that the Conoco gas field was the first of its kind taken by the Syrian Democratic Forces (SDF) - an alliance of Kurdish and Arab militias backed by the U.S. - since it began an offensive earlier this month to capture the eastern province.
Moscow also claimed that the SDF had diverted from the battle to take the northern city Raqqa to the province of Deir al-Zor, around 100 miles to the east, where Russian special forces are helping the Syrian army push out Isis militants.
Russian Federation said on Thursday it had warned the United States it would target areas in Syria where US special forces and USA -backed militia were operating if its own forces came under fire from them, something it said had already happened twice.More news: Politics not for votes for us: PM Modi

Syrian troops also crossed to the eastern side of the river on Monday where the SDF, an alliance of Kurdish and Arab militias fighting with the US -led coalition, has been advancing.
"According to our information, USA intelligence services initiated the offensive to halt the successful advance of government troops to the east of Deir al-Zor", said Colonel-General Sergei Rudskoi.
Days before that, the Syrian army had broken through Islamic State lines and reached an enclave held by the government in Deir al-Zor.More news: Korea minister says may consider H-bomb test in Pacific: Yonhap
