The US military's Central Command spokesman Colonel John Thomas said that Shayrat's runways were deliberately avoided because the United States was trying to draw a clear line that its military action was in response to the suspected chemical attack, and not signal a willingness to get more involved in Syria's brutal civil war.
The chemical attack on Khan Sheikhoun killed at least 87 people, including many children, and images of the dead and of suffering victims provoked global outrage.
The US warned Moscow via a pre-established military-to-military communications channel in advance of its April 6 cruise missile strike in order to prevent any Russian casualties.
Lieberman also refused to go into detail but said "We have 100 percent information that Assad regime used chemical weapons against rebels".
Meanwhile, the presidential advisor said that the U.S. is in a state of declination, while Russia, China and India are rising high.
An Israeli assessment has found that Mr Assad's regime was still in possession of "a few tonnes" of chemical weapons, a military official confirmed.
We review the key developments in Syria, including a chemical weapons prohibition watchdog confirming the use of sarin in the attack on Khan Sheikhoun, the Syrian government moving its jets from Shayrat to a Russian base in Latakia, and delays to convoys of evacuees from Fuaa, Kafraya and Zabadani.More news: Protesters around country call for Trump to release tax returns
Syrian President Bashar al-Assad still possesses up to three tons of chemical weapons, Israeli defense officials have said.
Russia, a key ally of the Syrian government, said it would stop engaging in a hotline with the USA military used to "deconflict", or to make efforts to avoid collisions in Syrian airspace.
Even if given a similar warning, it is unlikely that Russian forces would willingly vacate Hmeimim - a base Moscow has leased from the Syrian government and considers to be its own. The fighting has killed an estimated 400,000 people and displaced half of Syria's population.
British Secretary of State for Foreign and Commonwealth Affairs Boris Johnson has said Britain could join USA air strikes against the Bashar al-Assad's regime in Syria despite a previous vote in the parliament against it. Reminding of then-US Secretary of State Colin Powell's white powder vial at the United Nations and other allegations of the chemical weapons "threat" in Iraq it has said that special equipment to collect samples for further scientific analysis should be used at the airfield, adding that Russian Federation has already undertaken similar procedures in Aleppo, Syria where it said chemical weapons had been used by militants.
The attempt by Western countries to derail Russia's fact-finding initiative in Syria to examine the site of the chemical incident in Idlib province exposes their aim to topple the Syrian government, Russian Foreign Minister Sergey Lavrov said. But doubts began to emerge soon afterward that not all such armaments or production facilities were declared and destroyed.
Israel welcomed the strike on its northern neighbour.
Brig. -Gen. Zaher al-Sakat, the former head of Syrian's chemical warfare who defected in 2013, said Assad had amassed at least 2,000 tons of chemical weapons, not 1,300 as he claimed, Israel's The Tower quoted Britain's The Telegraph.
