Former U.S. President Donald Trump criticized current U.S. President Joe Biden in a social media post for overseeing military operations in the Middle East while Defense Secretary Austin was managing operations remotely from a hospital room.

According to "Sputnik" agency, Trump said on social media: "Let me make this clear. We are dropping bombs all over the Middle East, again where I defeated ISIS!, and our Defense Secretary, who just disappeared for five days, is running the war from his laptop in the hospital room."

He added: "Remember this is the same gang that surrendered in Afghanistan, where no one was held accountable or fired... It was the most embarrassing moment in U.S. history... And now we also have wars in Ukraine... Joe Biden is the worst president in U.S. history."

In the early hours of Friday, the United States and the United Kingdom carried out airstrikes against Houthi positions in response to attacks on commercial ships in the Red Sea.

The U.S. Air Force said the strikes hit more than 60 targets at 16 different locations.

Russia condemned the airstrikes on Yemen carried out without a United Nations mandate, describing them as a direct threat to peace and security.
