"The Embassy expresses its deepest condolences to the families and friends of those killed in a series of devastating tornadoes that struck the central regions of the United States", the embassy said in a Facebook statement on Saturday, wishing "a speedy recovery to the victims of the disaster".
Late on Saturday, US President Joe Biden said at a briefing that this week's string of over 30 deadly tornadoes was "likely one of the largest tornado outbreaks in our history".
The president said he had discussed the situation with the governors of Arkansas, Illinois, Kentucky, Missouri, and Tennessee.
Biden declared a state of emergency in Kentucky, where over 70 people died because of the storms, according to Governor Andy Beshear. The Kentucky death toll could actually exceed 100, Beshear told reporters on Saturday morning.
