"They are hard for us, but will do more damage to the United States of America and Europe", RIA quoted Serebrennikov as saying.
The action followed a week of threats of retaliation for a suspected chemical weapons attack on civilians in Douma, outside Damascus, where Syrian forces have always been battling rebels.
Syria and its ally Russia have denied such an attack took place, and Moscow has accused Britain of helping to stage the Douma incident to stoke anti-Russian hysteria.
Following the USA -led strikes, however, "we consider it possible to return to examination of this issue not only in regard to Syria but to other countries as well", Rudskoi said.
Syria ally Russian Federation has warned of "consequences" following the launch of US-led strikes against Bashar al-Assad's regime in retaliation for a suspected chemical attack.
"The worst fears were justified: our warnings were ignored, a script prepared in advance is being put into practice, and again we are threatened".
House Speaker Paul Ryan is praising Trump's "decisive action in coordination with our allies", adding, "We are united in our resolve".
"Insulting the President of Russia is unacceptable and inadmissible", added the envoy, after President Donald Trump directly called out his Russian counterpart Vladimir Putin over his support for the Assad regime. "You need to be really exceptional to shell Syria's capital at the moment when it had gained a chance of a peaceful future".
"The US - the possessor of the biggest arsenal of chemical weapons - has no moral right to blame other countries".
