Saudi Arabia to conduct anti-ISIS multinational military training exercise - CNN

Two Saudi officials told CNN that the kingdom plans to run in March a multinational military training exercise -- involving as many as 150,000 troops -- to prepare for future anti-ISIS operations.

Most of the personnel will be Saudis; troops from Egypt, Sudan and Jordan have already arrived in the kingdom for the exercise, and troops from other countries -- Morocco, Turkey, Bahrain, the United Arab Emirates and Qatar -- are expected, the officials said.

On Thursday, Saudi Brig. Gen. Ahmad al-Asiri, a military adviser to the kingdom’s defense minster, said that the Saudis are willing to send -- as part of an international coalition -- ground troops into Syria to fight ISIS. 

Saudi Arabia also participates in a U.S.-led coalition conducting airstrikes against ISIS in Syria.
