"As a result of "operation Olive branch" March 12, began the siege of the Syrian city of Afrin", - said in the message. The Turkish offensive opened a new front in a multi-sided civil war now entering its eighth year, which has drawn in neighbours and global powers who have armed and assisted fighters on the ground.
The Turkish military said in a statement that it had completed the encirclement of the city of Afrin, home to some 350,000 people and defended by a well-armed Syrian Kurdish militia, the People's Protection Units (YPG).
The Syrian Observatory for Human Rights said Turkish forces were within firing range of that route, which leads to a pair of regime-held towns - essentially encircling Afrin and 90 villages to its west.
Turkey's army and allied Syrian rebel forces have surrounded the city of Afrin in northwestern Syria, the main target of Turkey's operation there. In addition to Turkish forces being around the city, they are also said to be shelling all roads leading into Afrin, preventing any reinforcements getting in the city to resist Turkey's invasion.
It remains unclear what Turkey's next move will be, with some analysts suggesting it will be content to lay siege to Afrin for some time while allowing civilians to leave to avoid a high-casualty offensive.
Forces loyal to President Bashar al-Assad have meanwhile been pressing an assault to retake the opposition-held enclave of Eastern Ghouta, the last major rebel stronghold near to Damascus. At least 353,935 people have died since, including more than 106,000 civilians, according to the Observatory.
