US President Barack Obama plans to deploy another 250 soldiers to Syria to support forces in the fight against ISIS.
The announcement comes after the US Department of Defense's (DoD) strategy for the next phase of the fight against ISIS in Iraq.
The DoD aims to deploy 217 additional advisers with the Peshmerga to support an assault on the ISIS stronghold of Mosul, Iraq.
Obama has ruled out the use of US ground troops and plans to send non-combat forces to Syria, the BBC reported.
BBC quoted Obama as saying: "It would be a mistake for the United States, or Great Britain ... to send in ground troops and overthrow the Assad regime."
The decision will increase the number of US personnel in non-combat roles in Syria from 50 to 300, The Wall Street Journal reported.
According to the Associated Press, the majority of the additional personnel will be special operation forces.
The non-combat forces will also include medical and logistics support personnel.
Since 2011, the ongoing conflict in Syria has killed more than 250,000 people and displaced around 11 million others.
Obama was further quoted by the BBC as saying: "In order for us to solve the long-term problems in Syria, a military solution alone - and certainly us deploying ground troops - is not going to bring that about."
