Trump tells Russia to 'get ready' for Syria missile strikes

Syria's Assad warns Western action would'further destabilise region

He also said a clash "should be ruled out and therefore we are ready to hold negotiations".

The US was still assessing intelligence about the chemical attack to ascertain whether Syrian forces were responsible or not, said US defence secretary Jim Mattis on Wednesday, shortly after Mr Trump tweeted that an attack on Syria was imminent.

Shamanov emphasized that a retaliatory Russian strike could target US navy ships and aircraft. (AAP) The suspected chemical attack in Syria killed at least 40 people.

The tweets will no doubt put the pressure on Theresa May who has yet to back air strikes on Syria even though she said on Tuesday that she would not "allow the use of chemical weapons to continue".

Vladimir Shamanov, a retired general who heads the defence affairs committee in the lower house of parliament, said in televised remarks Tuesday that a USA strike in Syria could hurt Russian servicemen and trigger retaliation.

President Donald Trump told Russia Wednesday to "get ready", saying missiles "will be coming" to Syria following a suspected chemical attack.

"As before we would hope that all sides will avoid steps that in reality are not provoked by anything and that could destabilize the already fragile situation in the region", Kremlin spokesman Dmitry Peskov said.

Since Trump tweeted about striking Syria, Syrian forces have moved around assets to shield them from United States missiles, possibly blunting the potential effect of the strike.

The Russian embassy in The Hague said it had passed along a proposal to the OPCW from Moscow "to immediately launch the investigation".

Prior to the tweet, Russian Federation said its air defenses would shoot down any incoming missiles and that its forces would retaliate against the source of any attacks. "Smart missiles should fly toward terrorists, not the legal government that has been fighting global terrorism for several years on its territory", Russian Foreign Ministry spokeswoman Maria Zakharova said in a Facebook post.

Donald Trump warned Russian Federation that U.S. missiles to Syria "will be coming, nice and new and "smart!" in a tweet Wednesday morning".

Last year, Trump launched a cruise missile strike against a Syrian air base in retaliation for a sarin attack the United Nations later pinned on Assad. Get ready Russian Federation, because they will be coming, nice and new and "smart". "Could be very soon or not so soon at all!", Trump tweeted.

Bouthaina Shaaban told al-Mayadeen that the Syrian government and its main ally Russian Federation had made preparations after Israel's strike on Sunday against the T-4 airfield near Homs, the channel reported.

The President previously criticised the Obama Administration for telegraphing its military moves in advance.

It prompted a slew of Russian comments that warned that USA strikes could trigger a direct military clash between the two former Cold War adversaries. In the past Trump has vowed to stand up to Syrian President Bashar Assad.

Syrian Army has discovered where the White Helmets have filmed their propaganda videos in Eastern Ghouta against the Syrian government, a report said on Wednesday.
