Saudi Arabia's king presented President Donald Trump with the kingdom's top civilian honour on Saturday as Trump began a trip to Riyadh aimed at strengthening security and economic ties.

Dogged by controversy at home, Donald Trump opened his first presidential foreign trip in Saudi Arabia on Saturday and won a warm reception as he looked to shift attention from a political firestorm over his firing of former FBI Director James Comey.
Saudi King Salman bin Abdulaziz greeted him on a red carpet as he stepped off Air Force One, shaking the hand of his wife, Melania, and riding in the presidential limousine.
It was a warmer welcome than had been granted to Trump's predecessor, Barack Obama, who was seen in the Arab kingdom as soft on Iran and hesitant on Syria.
Trump's trip to Saudi Arabia, Israel, Italy, the Vatican and Belgium has been billed by the White House as a chance to visit places sacred to three of the world's major religions, while giving Trump time to meet with Arab, Israeli and European leaders.
But uproar in Washington cast a long shadow over the trip. The president's firing of Comey and the appointment of a special counsel to investigate his campaign's ties to Russia last year have triggered a stream of bad headlines.
The New York Times reported Trump had called Comey a "nut job" in a private meeting last week in the Oval Office with Russian Foreign Minister Sergei Lavrov and ambassador to the United States Sergei Kislyak.
The White House did not deny the report, but said "the real story is that our national security has been undermined by the leaking of private and highly classified conversations."
In another development, the Washington Post said a current White House official close to Trump was a significant "person of interest" in the investigation into possible ties between Trump's presidential campaign last year and Russia.
Trump and King Salman seemed at ease with each other, chatting through an interpreter. At the royal al-Yamama palace, the king decorated Trump with the King Abdulaziz medal, the country's top civilian honor.
The two leaders exchanged tweets, Trump saying it was great to be in Riyadh and King Salman welcoming him.
"Mr. President, your visit will strengthen our strategic cooperation, lead to global security and stability," King Salman said in a message on his official Twitter account in Arabic and English.
Trump’s decision to make his first official trip abroad to Saudi Arabia, followed by Israel, countries which both share his antagonism towards Iran, marks a contrast with Obama's approach.
