Excitement is building in the Netherlands a day before Crown Prince Willem-Alexander will be named king. Queen Beatrix will abdicate the throne Tuesday, and when the prince is sworn in, he'll become the first Dutch king in 122 years.

The transition will take place April 30, a national holiday known as Queen's Day — a busy holiday in any year in the Netherlands and especially popular in 2013. It will be renamed King's Day during the reign of Willem-Alexander, and moved to April 27, the new king's birthday.

Iraqi officials have suspended the right of 10 satellite TV channels to operate in the country, as media regulators say the stations' coverage of sectarian conflicts incites more violence.

Less than a week after mandatory furloughs began that idled as much as 10 percent of U.S. air traffic controllers, the Federal Aviation Administration has ended its furlough program. The move comes after Congress voted to let the FAA move money around in its budget — a quick response that came after several days of travel delays that were either caused by or worsened by the furloughs.

In a statement released Saturday, the FAA said that it is suspending furloughs for all its employees.

Sectarian tensions are fueling violence and protests in Iraq, where more than 170 people have been killed since Tuesday, when government forces clashed with Sunni Muslim protesters at a demonstration camp in Hawija, near Kirkuk.

That incident left at least 23 dead, outraged Iraq's Sunni minority, and stoked fears among some Iraqis that their country is heading for a new civil war. Several deadly attacks have been staged on Iraqi soldiers and police this week.

Federal agents who are investigating poison-laced letters that were sent to President Obama and others have arrested Everett Dutschke, of Tupelo, Miss. The Daily Journal of Tupelo reports that the arrest occurred around 1 a.m. Saturday.

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."

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.
