Pro-Iran armed groups in Syria attacked two American bases in the east of the country on Saturday, December 30, in response to “probable Israeli strikes” carried out earlier in the day. Washington immediately retaliated.

Armed groups affiliated to Iran targeted two American bases in the Syrian province of Deir ez-Zor on Saturday evening, according to the Syrian Observatory for Human Rights (SOHR). Nearly forty rockets were fired at the bases, the NGO said.

US forces immediately retaliated by launching air strikes against the sites occupied by these groups.

This escalation of tensions follows the deaths of nineteen Iranian-affiliated fighters earlier in the day, as well as around twenty injured in “probably Israeli” air strikes against sites in eastern Syria, according to information reported by the SOHR.

The Syrian NGO said “19 pro-Iranian fighters including four Syrians and six Iraqis were killed, and more than 18 were wounded” in at least nine air strikes overnight near the Iraqi border.

“Likely carried out by Israel”

It said the raids were “likely carried out by Israel”, after earlier indicating they were “likely American.”

A US military official, requesting anonymity, said the “US did not conduct any defensive strikes overnight.”

Israel rarely comments on individual strikes targeting Syria, but it has repeatedly said it will not allow arch-foe Iran, which backs President Bashar al-Assad’s government, to expand its presence there.

The Observatory said the strikes targeted military positions in Albu Kamal and its surroundings in the Deir Ezzor province, adding that a weapons shipment from Iraq and an ammunition warehouse were also hit.

Separately, “Israeli ground bombardment” overnight in southern Syria’s Quneitra province, near the Israeli-occupied Golan Heights, killed two fighters from a Hezbollah-linked group, said the Britain-based monitor.

The pair, “of Palestinian origin,” were “members of a group affiliated with the Syrian Resistance to Liberate the Golan, which works with Hezbollah,” according to the Observatory, which has a broad network of sources inside war-torn Syria.

The Observatory also announced in the afternoon that Iranian militia warehouses and headquarters in the Aleppo Airport area had been targeted by strikes from the sea, killing at least 7. “Most of those killed were Hezbollah members”, added the SOHR.

Hezbollah fighters killed

During more than a decade of civil war in Syria, Israel has launched hundreds of air strikes on its territory, primarily targeting Iran-backed forces including Hezbollah fighters as well as Syrian army positions.

But it has intensified attacks since the war between Israel and Hamas began on October 7, as tensions rise across the Middle East.

The Israeli army had said early Saturday that it was carrying out strikes in Syria after two rockets fired from the country fell into territory under its control.

The army did not say the precise location where they fell.

Hezbollah movement, which like Hamas in the Gaza Strip is supported by Iran, announced on Saturday the death of four of its fighters “on the road to Jerusalem” — a reference to militants killed in hostilities since October 7.

It was unclear where they were killed.

Iranian state media said an Israeli missile strike on Monday near Damascus killed Razi Moussavi, a senior commander in the Quds Force, the foreign operations arm of Iran’s Islamic Revolutionary Guard Corps.

The Middle East has also seen a surge in attacks on US forces, which Washington blames on Tehran-aligned armed groups across the region, since the start of the Israel-Hamas war.

The majority have been claimed by the Islamic Resistance in Iraq, a loose formation of Iran-linked armed groups that oppose US support for Israel.

The United States launched air strikes in Iraq this week after a drone attack in the Kurdistan region wounded three US military personnel, one critically.

In mid-November, at least eight members of Tehran-linked groups were killed in US strikes that hit two sites in Deir Ezzor province, according to the Observatory.
