Iran: US actions in Middle East cannot remain without response

Iran's parliament speaker Ali Larijani denounced US President Donald Trump as "feeble-minded" over Monday's controversial move of the US embassy to Jerusalem, calling for resistance from the Palestinians and the international community.

"America has entered a crisis of strategic decision-making that looks at the international arena immaturely and adventurously," the parliament speaker said at a conference on the Palestinian situation in Tehran.

"I believe the current US president is not capable of identifying and judging the long-term consequences of his actions," AFP cited him as saying.

"Spur-of-the-moment and uncalculated actions cannot continue in today's world. Feeblemindness is costly for statesmen and they will eventually have to pay the price," Larijani said.

Larijani called for an "immediate reaction" from Palestinians, Islamic countries and the international community - including boycotts and official complaints to the United Nations.

The US "must not think that such actions... can remain without a response," he said.

The United States was due to open its new embassy in Jerusalem later on Monday amid widespread Palestinian anger and praise from Israelis.
