Iran's newly re-elected President Hassan Rouhani on Monday dismissed his US counterpart Donald Trump's summit with Arab leaders in Saudi Arabia this weekend as "just a show". 
"The gathering in Saudi Arabia was just a show with no practical or political value of any kind. You can't solve terrorism just by giving people's money to a superpower," Rouhani said at a press conference on Tehran, referring to the billion-dollar deals signed between the US and Saudi Arabia.
