A senior Iranian official has said that Washington plays no effective role in fighting terrorism in the region.

Iranian Parliament's General Director for International Affairs Hossein Amir-Abdollahian said the United States, whether under Obama or Trump has not taken any effective measure to combat terrorism in the Middle East.

Abdollahian said on Sunday that the Trump administration is not different from the previous administration, and that the U.S. continues its counterproductive behavior in the region.

Since he took office in January, Trump has intervened in various countries, including Syria, Yemen, Iraq and Afghanistan.

In April, the U.S. carried out a missile attack against a Syrian airbase after Washington accused Syrian government of conducting a chemical attack in Idlib, a claim that the Syrian government has rejected as false.

Following the alleged chemical attack, Trump said, “I think what Assad did is terrible. I think what happened in Syria is one of the truly egregious crimes. It shouldn't have happened. It shouldn't be allowed to happen.”

It came after the Syrian army succeeded in pushing back the foreign-backed militant groups from key regions in the country.

Trump’s attack against Syria encouraged his Democratic opponents to come to his side, cheering the new president for his military misadvanture in other countries.
