The US airstrike last Wednesday in Syria on a weapons storage facility linked to Iran caused no casualties, a Pentagon spokesman said Thursday, contradicting information from a non-governmental organization that said nine people were killed.

The day before yesterday, two US warplanes struck a facility in northeastern Syria and hit a “weapons depot”, in retaliation for attacks on US personnel in Syria and Iraq, according to Washington.

“As of this moment, we have not recorded any losses,” Sabrina Singh, the Pentagon’s deputy spokeswoman, told accredited reporters yesterday.

This statement contradicts the information of the Syrian Observatory for Human Rights, which yesterday Wednesday spoke of nine dead, adding that the victims belonged to organizations supported by Iran.

On October 26, the US military struck two more facilities in Syria that it said were being used by Iran and organizations close to it. And in that case, Washington had reported that the strikes had no victims.

This is retaliation by Washington due to the proliferation of attacks by pro-Iranian organizations against US troops in Syria and Iraq against the background of the war in the Gaza Strip. The US government is supporting Israel militarily in its conflict with Hamas.

In total, the US government counts 46 drone or rocket attacks against US troops in Iraq and Syria since October 17, including 4 after yesterday’s strike in eastern Syria.

Those attacks caused minor injuries to 56 US military personnel, according to Ms Singh.

Washington keeps about 900 of its troops deployed in Syria and another nearly 2,500 in Iraq as part of operations against the Islamic State (IS) jihadist group.
