British MPs voted down taking military action against Damascus in 2013, in what was widely viewed as an assertion of parliamentary sovereignty on the use of force.
"This collective action sends a clear message that the worldwide community will not stand by and tolerate the use of chemical weapons", May told a press conference.
"And a significant body of the information including intelligence indicates the Syrian Regime is responsible for this latest attack".
In a combined operation, the US, Britain and France on Friday launched military strikes against Bashar al-Assad's Syrian regime, President Donald Trump announced, as he alleged the war-torn nation of using chemical weapons against its own people.
Even this week, the Russians vetoed a Resolution at the UN Security Council which would have established an independent investigation into the Douma attack.
"We must reinstate the global consensus that chemical weapons can not be used".
May is expected to reiterate that the strikes were in the "national interest".
"This persistent pattern of behaviour must be stopped - not just to protect innocent people in Syria from the horrific deaths and casualties caused by chemical weapons, but also because we can not allow the erosion of the worldwide norm that prevents the use of these weapons".
"Now that the US, France and the United Kingdom have decided on their reaction to the use of chemical weapons last weekend, the need for a diplomatic offensive is more imperative than ever". It will be up to Speaker of the House of Commons John Bercow to decide whether to allow an emergency debate, and he has been a strong advocate of the right of Parliament to scrutinize the government. No wonder the government think they can negotiate Brexit trade deals in less than two years.
"They will only increase the likelihood of this bad conflict spilling over into the wider Middle East and potentially beyond that", CND said.
United Kingdom says Syria strikes were 'successful'
The SNP has told Sky News it would support the act.
United Kingdom prime ministers do not legally need to consult Parliament before launching military action, although they have done so since the 2003 invasion of Iraq.
When asked if there would be more military action against Syria, Williamson said he thought the Western strikes had so far had sufficient effect.
According to the expert, the aggression by Washington, London and Paris against Syria on Saturday was not aimed at changing the alignment of forces and from this viewpoint nothing changed.
Liberal Democrat leader Vince Cable said that "riding the coat-tails of an erratic United States president is no substitute for a mandate from the House of Commons", parliament's elected lower house.
The US president said America, being the world's greatest and most powerful economy, has a lot to offer.
British Prime Minister Theresa May described the strike as "limited and targeted".
"Vladimir Putin, in particular, stressed that if such actions committed in violation of the UN Charter continue, then it will inevitably lead to chaos in worldwide relations", the Kremlin said.
"Liberal Democrats stood ready to assess the evidence and objectives for any action and, if it were properly planned and justified, to support a military response".
Foreign Minister Boris Johnson, however, backed May's decision.
U.S. bans American companies from selling to Chinese phone maker ZTE
ZTE has been buying the hardware from the USA companies and using in its products which are later shipped to Iran and North Korea. The U.S. action against ZTE is likely to further exacerbate current tensions between Washington and Beijing over trade.
