The Trump administration has considered new military action against the Syrian government in response to reports of ongoing chemical weapons use, officials said, raising the prospect of a second U.S. strike on President Bashar al-Assad in less than a year, The Washington Post reports.

U.S. President Donald Trump requested options for punishing the Assad government after reported chlorine gas attacks — at least seven this year — and possibly other chemicals affecting civilians in opposition-controlled areas.

In a Feb. 25 incident, residents and medical staffers in a rebel-held Damascus suburb, Eastern Ghouta, described symptoms associated with chlorine exposure. One child died, medical staffers reported.

The president discussed potential actions early last week at a White House meeting that included Chief of Staff John F. Kelly, national security adviser H.R. McMaster and Defense Secretary Jim Mattis, officials said.

One official, who like others spoke on the condition of anonymity to address internal deliberations, said that the president did not endorse any military action and that officials decided to continue monitoring the situation.

Dana White, chief Pentagon spokeswoman, denied that Mattis took part in discussions about military action in Syria and said the “conversation did not happen.”

One senior administration official said that Mattis was “adamantly” against acting militarily in response to the recent chlorine attacks and that McMaster “was for it.”
