Saudi officials have stated that they want to fight ISIS and see President Bashar al-Assad removed

Saudi Arabia has reportedly sent troops and fighter jets to Turkey’s Incirlik military base ahead of a possible ground invasion of Syria, according to a report by the Associated Press news agency.
The Turkish foreign minister, Mevlut Cavusoglu, confirmed the deployment on Saturday morning, Feb. 13 in a statement to the Yeni Şafak newspaper.
“Saudi Arabia declared its determination against Daesh (the Arabic term for Isis) by saying that they were ready to send both jets and troops,” he said.
“At every coalition meeting we have always emphasized the need for an extensive result-oriented strategy in the fight against the Daesh terrorist group.
“If we have such a strategy, then Turkey and Saudi Arabia may launch an operation from the land,” Turkish foreign minister said. 
He confirmed that planes and military personnel were being sent to Incirlik, in Adana near the Syrian border, but said numbers had not been confirmed.
