Ah, here we go:
"In reality, Trump was attending the opening of the Global Centre for Combating Extremist Ideology along with Saudi Arabia King Salman bin Abdulaziz al-Saud and Egyptian President Abdel Fattah al-Sisi when the photo was taken. The state-of-the art centre aims to monitor and combat global extremism in real time. During the opening, the leaders in attendance placed their hands on an illuminated globe as a gesture of their combined commitment to ending terrorism, and to officially activate the centre by launching a welcome video on the screens above."
