In a move that has sent shockwaves across the global political landscape, US President Donald Trump has landed in Saudi Arabia, kicking off a highly anticipated tour of Gulf states.

The high-stakes trip, which will also take Trump to Qatar and the United Arab Emirates, is expected to yield lucrative deals worth over $1 trillion, according to sources close to the President.

Trump's visit to Riyadh, the capital of Saudi Arabia, marks a significant moment in the country's history, as the US seeks to strengthen its ties with key regional allies in the face of growing tensions with Iran.
