British Prime Minister Theresa May won backing from her senior ministers to take unspecified action with the United States and France to deter further use of chemical weapons by Syria after a suspected poison gas attack on civilians.
The BBC said May was ready to give the go-ahead for Britain to take part in action led by the US without seeking prior approval from parliament, and the Financial Times said the cabinet had agreed to this.
As US President Donald Trump warned that missiles "will be coming" and France weighs strikes, May will reportedly seek her ministers' approval to join allies in targeting President Bashar Assad's regime.
The condemnation by the United Kingdom and France followed earlier worldwide reaction to the attack in Douma.
Britain has launched air strikes against Islamic State militants in Syria, but not against the country's government.
Some lawmakers have expressed reservations about taking military action now, but others have come to believe the 2013 vote was a mistake.
The cabinet is expected to support May to join a possible military action by the US and its allies against the Syrian regime without seeking a parliamentary approval.
Syria's been fighting civil war for over seven years. By going to war with Syria, we would also be entering into a proxy war with Russian Federation, which is not only unsafe for Britain but the entire world.
Some MPs have backed Britain acting against Syria, warning that the use of chemical weapons was in breach of worldwide law and could not be allowed to go unpunished.
Some members of May's Conservative party have urged caution of intervening in a highly complex situation with many different players. She changed her tone speaking to reporters Wednesday afternoon, insisting that "all the indications" were that the Assad regime was responsible for the "shocking, barbaric" attack. The statement made no specific reference to military action. Specifically the govt needs to explain who is strengthened if and when Assad is weakened.
