National Security Adviser John Bolton said the U.S. is working with Britain and France to plan a coordinated attack against Syrian President Bashar al Assad's government should he use chemical weapons during an expected offensive in Idlib province. The U.S. conducted airstrikes against the regime in April 2017 and April 2018 after Assad was accused of using chemical weapons against civilians, and Bolton said Monday that France and the U.K. agreed that "another use of chemical weapons will result in a much stronger response." Russia has already launched 70 airstrikes in the province and the Syrian government has dropped dozens of barrel bombs. An estimated three million civilians and 70,000 opposition fighters are in Idlib, the last rebel-held part of Syria.
