Ten Russian servicemen have been killed fighting in Syria so far this year, according to statements from the Defence Ministry.

But based on accounts from families and friends of the dead and local officials, Reuters estimates the actual death toll among Russian soldiers and private contractors was at least 40.

That tally over seven months exceeds the 36 Russian armed personnel and contractors estimated by Reuters to have been killed in Syria over the previous 15 months, indicating a significant rise in the rate of battlefield losses as the country's involvement deepens.(For a graphic on Russian casualties in Syria's conflict click tmsnrt.rs/2hjq3Et)

Most of the deaths reported by Reuters have been confirmed by more than one person, including those who knew the deceased or local officials. In nine cases, Reuters corroborated a death reported in local or social media with another source.

The data may be on the conservative side, as commanders encourage the families of those killed to keep quiet, relatives and friends of several fallen soldiers, both servicemen and contractors, said on condition of anonymity.

The true level of casualties in the Syrian conflict is a sensitive subject in a country where positive coverage of the conflict features prominently in the media and ahead of a presidential election next year that incumbent Vladimir Putin is expected to win.

The scale of Russian military casualties in peace time has been a state secret since Putin issued a decree three months before Russia launched its operation in Syria. While Russia does not give total casualties, it does disclose some deaths.

Discrepancies in data may be explained partly by the fact that Russia does not openly acknowledge that private contractors fight alongside the army; their presence in Syria would appear to flout a legal ban on civilians fighting abroad as mercenaries.

Asked about Reuters' latest findings, the Defence Ministry and Kremlin did not respond.

The government has previously denied understating casualty figures in Syria, where Moscow entered the conflict nearly two years ago in support of President Bashar al-Assad, one of its closest Middle East allies.

Months after soldiers die, Russia quietly acknowledges some losses, including private military contractors. Their families get state posthumous medals and local authorities sometimes name schools, which fallen soldiers attended as children, after them.

Of the 40 killed, Reuters has evidence that 21 were private contractors and 17 soldiers. The status of the remaining two people is unclear.
