The Ministry of Defence said that "initial indications are that the precision of the weapons and meticulous target planning have resulted in a successful attack".
US, British and French forces hit Syria with more than 100 missiles in the early hours of Saturday in the first coordinated Western strikes against the Damascus government, targeting what they said were chemical weapons sites in retaliation for a suspected poison gas attack.
The missile strike that Trump was referring to occurred on Friday night. Bush addressed sailors aboard a ship in May 2003 alongside a "Mission Accomplished" banner, just weeks before it became apparent that Iraqis had organized an insurgency that tied down USA forces for years.

However, Lieutenant-General Kenneth McKenzie, right, head of the joint staff at the Pentagon, urged caution. It is about ISIS and deterring Assad's use of chemical weapons.
"To succeed in the long run, we need a comprehensive strategy for Syria and the entire region", Republican Senator John McCain said in a statement after the latest strikes.
While there appears to be no immediate alternative to the so-called Geneva Process that would lead to a political transition in Syria, several senior USA officials, speaking on condition of anonymity, insisted it has failed and it was time to rethink.
Haley said the joint military strike "put a heavy blow into their chemical weapons program, setting them back years" and reiterated that if Assad uses poison gas again, "the United States is locked and loaded". The NATO alliance gave its full backing; NATO Secretary-Normal Jens Stoltenberg mentioned in Brussels that the assault was about guaranteeing that chemical weapons can't be used with impunity.More news: NASA set to launch new planet hunting telescope
President Trump claimed over and over during the 2016 campaign, despite copious evidence to the contrary, that he had opposed the Iraq War.
Trump did the same on Friday, with allies France and Britain, in a response meant to deter Syrian President Bashar al-Assad from using chemical weapons again, but which was unlikely to change his grip on power.
McKenzie said 105 U.S. and allied missiles were fired, of which 66 were Tomahawk cruise missiles launched from aboard three U.S. Navy ships and one Navy submarine.
A global chemical warfare watchdog group, the Organization for the Prohibition of Chemical Weapons, said its fact-finding mission would go on as planned in Douma.More news: De Bruyne lauds mentally tough City after slaying Spurs
But British Prime Minister Theresa May said there was little doubt the Syrian government used a barrel bomb - large containers packed with fuel, explosives and scraps of metal - to deliver the chemicals at Douma.
