US President Donald Trump signed a host of economic and bilateral co-operation agreements in Saudi Arabia today, kicking off a four-day Middle East trip.

The countries’ positions on Iran’s nuclear ambitions and Israel’s invasion of Gaza were largely set aside, as the visit focused on economic diplomacy.

Mr Trump was warmly welcomed by Crown Prince Mohammed bin Salman, the kingdom’s de facto ruler, on arrival at King Khalid International Airport in Riyadh.
