Deals, handshakes and Musk - Key moments in Trump's Saudi visit

US President Donald Trump has said the US has "no stronger partner" than Saudi Arabia during his first major foreign trip - a whirlwind visit of Gulf countries mainly focused on shoring up investment.

Day one of the trip saw the two sides announce a $142bn (£107bn) arms deal, as well as a raft of other investments that Saudi Arabia's crown prince said could eventually be worth $1tn.

During his trip he also announced the US would lift Syria sanctions.
