In his speech at the UN, US President Donald Trump blamed Tehran and Moscow for the "butchery" of the Syrian government. At the same time, he thanked Russia, Iran, and Syria for "slowing down" the offensive operation in Idlib, Sputnik reported.

"I want to thank Iran, Russia and Syria for at my very strong urging and request substantially slowing down their attack on the Idlib province," Trump said.

The US president expressed his hope that they would get the terrorists in Syria, adding, however, that the restraint of the attack should continue, as "the world is watching."

Trump addressed the recent decision of Moscow to strike a deal with Turkey to avoid a full-scale military operation by the Syrian army against the rebel-held city of Idlib.

Following the recent escalation of tensions between the US and Iran, Trump said that the sanctions against Tehran would be "tougher than ever before".

"All US nuclear-related sanctions will be in full force by early November. They will be in full force. After that, the United States will pursue additional sanctions, tougher than ever before, to counter the entire range of Iran’s malign conduct," Trump said.

He also criticized Iranian nuclear program, urging the international community to control Tehran on the issue.

"I ask all members of the Security Council to work with the United States to ensure the Iranian regime changes its behavior and never acquires a nuclear bomb," Trump said.
