North Thunder or (in Arabic: رعد الشمال) was a joint military exercise held in the Kingdom of Saudi Arabia with the participation of a 20 of Arab and Islamic countries notably the United Arab Emirates, Turkey, Egypt, Bahrain, Sudan, Jordan, Pakistan, Qatar, Kuwait, Morocco, Chad, Comoro Islands,Tunisia, Oman, Malaysia and Yemen in February 2016.
Purpose

The exercise aimed to raise the technical and combat efficiency of the units involved and improve logistics and readiness rates for the implementation of joint security and stability missions in the region, notably Syria. A spokesman for the Arab coalition forces, Ahmad Assiri, said the aim of the exercise is to achieve the highest level of preparedness, exchange expertise and promote coordination among the 21 participating countries.

It has also been suggested, considering the forces involved, that the exercise could be the beginning of a land assault on Syria in conjunction with the Turkish Land Forces invading Syria from the north. On 13 February The Independent reported that Saudi troops and fighter aircraft were deploying to Incirlik Air Base in Turkey in preparation for intervention in Syria, however this could simply indicate a Saudi recommitment to the Military intervention against ISIL which was downgraded following the Saudi Arabian-led intervention in Yemen. Possible direct involvement in the war in Syria has unsettled many Saudis as the war in Yemen appears to be a stalemate and the Saudi economy has been affected by low oil prices
