At least 125,835 people, including 4,454 women and 6,625 children, have died in Syria since the start of the civil war in 2011, the opposition Syrian Observatory for Human Rights said Monday.

The figure includes deaths that occurred from the first protests against President Bashar al-Assad's regime on March 18, 2011, to Dec. 1, the London-based group, which has a large network of activists on the ground across Syria, said.

The majority of the dead - 44,381 - are civilians, the human rights group said.

Some 27,746 opposition fighters, including 2,221 deserters from the Syrian military, have died in the conflict.

A large number of foreign fighters are among the dead, but exact figures are not available, the group said.

At least 31,174 armed forces members loyal to the Assad regime have been killed, while 19,256 pro-government militiamen and informants have died in the civil war, the human rights group said.

A total of 232 members of the Shiite Hezbollah group and 265 members of other Shiite groups have died fighting with troops loyal to Assad.

Some 2,781 unidentified people have been killed in the conflict, the human rights group said.

The death toll from Syria's civil war may be higher because the report does not include deaths among the 21,000 people being held in the Assad regime's prisons and detention centers for opposition members, the Syrian Observatory for Human Rights said.

The number of insurgents killed may be more than 40,000, but it has not been possible to obtain figures from the various armed groups, the human rights group said.

More than 100,000 people have died since the internal conflict started in Syria, the United Nations said in a report released in August. EFE
