Thousands of flights across the U.S. were delayed Monday, as severe thunderstorms in the South, Plains and Mississippi Valley disrupted traveling Americans during the Memorial Day weekend. As of 4:30 p.m. EDT on Monday, there were over 4,300 flight delays and more than 125 cancellations in and out of U.S. airports, according to FlightAware.

Severe weather upends Memorial Day travels for tens of millions of Americans as they try to get back home. Also, dozens hurt in the U.K. after a vehicle rams into the crowd near the Liverpool soccer team's victory parade.
