The Pentagon confirmed that the US military had conducted airstrikes against infrastructure utilized by Iranian-backed militant groups in eastern Syria.
"At President (Joe) Biden's direction, US military forces earlier this evening conducted airstrikes against infrastructure utilized by Iranian-backed militant groups in eastern Syria," the Pentagon said in a statement on Thursday, Xinhua news agency reported.
"These strikes were authorized in response to recent attacks against American and Coalition personnel in Iraq, and to ongoing threats to those personnel," it said, adding the strikes destroyed multiple facilities located at a border control point used by a number of Iranian-backed militant groups.
Thursday's airstrikes also came at a time when the Biden administration, which reportedly plans to bring the United States back to the 2015 Iran nuclear deal that the Donald Trump administration pulled out of, said it was ready to engage in negotiations with Iran over the nuclear issue.
Syrian govt condemns US overnight strike
The Syrian Foreign Ministry strongly condemned the US strikes that targeted positions in eastern Syria before Friday's daybreak, state news agency SANA reported.The US strikes in the eastern province of Deir al-Zour near the Iraqi border killed 22 pro-Iran Iraqi fighters who were providing support for the Syrian government forces, according to the pro-rebel Syrian Observatory for Human Rights, Xinhua news agency reported.
The attack undermines the international legitimacy in resolving the Syrian crisis and is part of the repeated aggression by the United States, Israel and Turkey on the sovereignty of Syria, the foreign ministry said.
Such attacks will only spread chaos, destroy the infrastructure in Syria, and play into the hands of the terrorist groups in Syria, it added.
The ministry accused Washington of supporting the Islamic State (IS) and the al-Qaida-linked Nusra Front in order for a pretext for the presence of US forces in Syria.
It also highlighted the Syrian government's determination to liberate all Syrian areas from the forces of occupation, including the areas controlled by the Kurdish militia in northeastern Syria and the Israeli-occupied Golan Heights.
