‘No doubt’ Syria responsible for deadly chemical attack: Mattis

The United States has “no doubt” that the regime of Syrian President Bashar al-Assad was responsible for last week’s chemical attack on a rebel-held town that left dozens dead, Pentagon chief Jim Mattis said Tuesday.

Mattis told reporters that Washington’s military strategy in Syria had not changed even after its retaliatory missile strikes on a Syrian air base, noting “our priority remains the defeat” of ISIS.

“There is no doubt the Syrian regime is responsible for the decision to attack and for the attack itself,” Mattis said.

“In response to the attack,” US national security officials came up with “diplomatic and military options” presented to President Donald Trump, said Mattis, who added that he also spoke with Washington’s allies.

“The National Security Council considered the international prohibition against the use of chemical weapons, the Syrian regime’s repeated violations of that international law and the inexplicably ruthless murders the regime had committed,” he said.

“We determined that a measured military response could best deter the regime from doing this again.”

The Pentagon chief also emphasized Washington’s focus on defeating ISIS extremists.

“ISIS represents a clear and present danger and immediate threat to Europe and ultimately a threat to the United States homeland,” he said.

Mattis’ comments came just after US Secretary of State Rex Tillerson arrived in Russia on Tuesday to confront the Kremlin over its support for Assad.

A US official speaking on condition of anonymity said Washington was investigating whether Russia was complicit in the alleged chemical weapons attack.
