The British Prime Minister Theresa May has called emergency meeting of her cabinet amid reports she is ready to give the green light for the United Kingdom to join any military action.
Referring to the allegation of a Russian military official that there was an attack, but it was staged by the White Helmets brigade component of the rebels in Syria, she said the intelligence provided "certainly paints" a different picture, and the President holds Syria and Russia responsible for the chemical weapons attack.
President Donald Trump huddled with top national security advisors Thursday to weigh his military options in Syria, as Moscow warned against any move that risks triggering a conflict between Russian Federation and the United States. She also said that no country should use chemical weapons and go unpunished.
Downing Street said the Prime Minister spoke to the U.S. and French presidents on Tuesday, and said they had agreed to "continue working closely together" to ensure those responsible were "held to account".

Opposition lawmakers have called on May to give Parliament a vote before committing British troops.
Mr Putin has also talked to the Israeli Prime Minister Benjamin Netanyahu, urging him not to take action to destabilise Syria and threaten its security.

Formally, the prime minister has the right to go to war without approval from parliament, but a convention has been established in previous conflicts where MPs have a vote either before or shortly after military action begins.
Twenty-one percent of the respondents said they did not know if it was necessary to hold a parliamentary vote on whether London should engage in the military actions against Syria.
But they backed action in Iraq the following year, and again in Syria in 2015, strictly limiting strikes to Islamic State (IS) group targets.
Asked to comment on possible US strikes, Peskov said "it's necessary to avoid any steps that may fuel tensions in Syria". "Could be very soon or not so soon at all!", the President tweeted.
