According to the Pentagon, however, 58 of the 59 Tomahawks hit their targets.

Moscow also accused that the Shayrat strike was “obviously” planned by the U.S. even before the chemical weapons attack on Tuesday.

“The preparation of such a strike is necessary to conduct a large range of activities for exploration, planning, preparation of flight missions and bringing the missiles into full readiness for launch. For any specialist, it is clear that a decision on the missile strike on Syria was taken in Washington long before the events in the village Khan Sheikhoun,” the statement explained.
