Riyadh- The Arab-Islamic-US Summit launched by Custodian of the Two Holy Mosques King Salman bin Abdulaziz in Riyadh on Sunday, in the presence of US President Donald Trump and scores of Arab and Islamic leaders, founded a collective action against extremism, terrorism and Iran, and culminated in the opening of the Global Center for Combating Extremist Ideology “EATEDAL.”

Addressing the summit from King Abdulaziz International Convention Center in Riyadh on Sunday, King Salman said “the Iranian regime has been the spearhead of global terrorism since the Khomeini revolt and until today.”

He added: “We have been in this country for 300 years and we never knew terrorism until the Khomeini revolution reared its head in 1979.”

The Custodian of the Two Holy Mosques said that the Iranian regime and its affiliated groups and organizations such as Hezbollah and the Houthis, as well as ISIS and Al-Qaeda are all similar.

The King accused Tehran of rejecting the initiatives of good neighborhood provided by Arab countries based on good faith.

“Iran replaced these initiatives with expansionist ambitions, criminal practices, interferences in the internal affairs of other countries, flagrant violations of the international law, and violations of the principles of good-neighborliness, coexistence and mutual respect,” King Salman said.

He stressed the need to foil terror financing, adding that Saudi Arabia would never be lenient in sending to justice whoever finances or supports terrorism in any form or under any manifestation as he would be subject to decisive justice.

For his part, President Trump held Iran responsible for “world terrorism,” and called for its isolation by saying: “No discussion of stamping out this threat would be complete without mentioning the government that gives terrorists all three—safe harbor, financial backing, and the social standing needed for recruitment. It is a regime that is responsible for so much instability in the region. I am speaking of course of Iran.”

Trump said that from Lebanon to Iraq to Yemen, Iran funds, arms, and trains terrorists, militias, and other extremist groups that spread destruction and chaos across the region.

“Until the Iranian regime is willing to be a partner for peace, all nations of conscience must work together to isolate Iran,” Trump said.

Also, the US President called on Muslim-majority countries to take the lead in combatting radicalization.

“A better future is only possible if your nations drive out the terrorists and extremists. Drive them out. Drive them out of your places of worship. Drive them out of your communities…,” Trump said.
