I want to know the answer to the following question:
Which side of the civil war did Nasser side with?
All the background I'm provided with is that "Al-Badr and his tribal partisans began receiving increasing support from Saudi Arabia to help reinstate the kingdom, while Nasser subsequently accepted a request by Sallal to militarily aid the new government on 30 September.". Is that enough to answer the question?
Answer: yes
