Paraguay's Nicolas Leoz resigned from FIFA's executive committee Tuesday, the same week an extensive report on bribery from the group's ethics investigator is to be released.

A 6-year-old boy's day off from school Friday left him with a vivid story to tell his classmates, after he was seized — and eventually released — by an alligator in South Florida. The attack occurred at a wildlife refuge near Boynton Beach, Fla., where Joseph Welch had taken his son, Joey, for a canoe ride.

As Welch, a native of Rhode Island who now lives in Pompano Beach, says in a Morning Edition interview airing Tuesday, his idea had been to do "something new and different."

Canadian authorities have disrupted an alleged plot that targeted a passenger train line running between New York and Toronto, the Royal Canadian Mounted Police announced Monday. The plan involved derailing a train, but police officials would give few details about the plot at a news conference this afternoon.

Many airline passengers saw only moderate flight delays stemming from the first full day of furloughs for nearly 15,000 flight controllers and other Federal Aviation Administration workers, as industry analysts' worst fears did not materialize. But the reduced staffing was blamed for some slowdowns, and observers say it also increased the length of unrelated delays.

We'll be keeping an eye on possible delays today, and updating this post with new information.

Update at 6:45 p.m. ET. Delays Build, Many Tied To Weather:

Towns in Missouri, central Illinois and at least four other Midwestern states are under a flood warning, as heavy spring rains swell the Mississippi and other rivers to dangerously high crests. In some areas, rivers have already hit record flood levels.

In places where residents have been forced to evacuate their homes, the American Red Cross has set up shelters at schools and other facilities.

Hundreds of Boston-area residents gathered Sunday to pray, to sing and to remember the victims of bombs and other violence in the city this week.

Boston bombing suspect Dzhokhar Tsarnaev has not yet been questioned — but officials' decision not to read him his Miranda rights before interrogation is the subject of much debate.

The London Marathon observed 30 seconds of silence before the race got underway Sunday, in a show of solidarity with the victims of Monday's attack at the Boston Marathon. Many runners and spectators wore black ribbons to honor the three people killed and the more than 170 injured in two bombings.

Watertown, Mass., resident David Henneberry's name was on many people's lips Saturday, as the hero who called police to say bombing suspect Dzhokhar Tsarnaev might be hiding in his back yard. Massachusetts State Police have now released images that show what the authorities saw from a police helicopter as a wounded Tsarnaev hid under a tarp.

After days spent living in a cloud of apprehension and fear following Monday's bomb attack at the Boston Marathon, the city's residents celebrated the capture of suspect Dzhokhar Tsarnaev on Friday night. He was caught hiding in a boat in the backyard of Watertown resident David Henneberry.

With Boston Marathon bombing suspect Dzhokhar Tsarnaev in police custody at Beth Israel Deaconess Medical Center and his brother and fellow suspect Tamerlan Tsarnaev dead after a shootout, many questions now focus on how these two young men arrived at this point.

What does it take to ride a bicycle at 100 miles per hour? That's the question being explored by Britain's Donhou Bicycles and frame builder Tom Donhou, who has mounted a mammoth chainring onto a custom bicycle. He says the steel machine has already hit 60 miles per hour on the open road.
