A teenager has been arrested on suspicion of posting malicious Twitter messages directed at British Olympic diver Tom Daley, UK police said Tuesday.

Daley's father died of brain cancer a year ago and the 18-year-old Olympian had hoped to win a medal "for myself and my dad." But he finished fourth on Monday, out of medal contention, in the 10-meter synchronized platform competition with teammate Pete Waterfield.

U.N. staff visited storm-pounded counties in North Korea on Tuesday, after two days of heavy rain submerged buildings, cut off power, flooded rice paddies and forced people and their livestock to climb onto rooftops for safety.

The rain Sunday and Monday followed downpours earlier this month that killed nearly 90 people and left more than 60,000 homeless, officials said. The floods also come on the heels of a severe drought, fueling renewed food worries about a country that already struggles to feed its people.

A Brazilian who won Olympic bronze in judo accidentally broke his medal when he took it to the shower with him. Now his fight is to have it replaced by the International Olympic Committee.

Felipe Kitadai said he was carrying the medal everywhere he went and decided to take it to the shower as well as a joke, but ended up dropping it while trying to keep it from getting wet.

Thanks to rain, Victoria Azarenka, Venus Williams and 20 other women at the Olympics who have yet to complete a singles match could end up on court six consecutive days if they reach the gold medal round.

Sunday showers at Wimbledon forced the postponement of 32 matches and the suspension of four others, meaning just one-quarter of the day's matches were completed. Rain delays often disrupt Wimbledon's two-week Grand Slam tournament, but the Olympic event at the All England Club is just nine days.

Government forces on Monday strafed rebel-held districts in Aleppo with helicopter gunships and pounded them with shelling on the third day of a pitched battle for Syria's commercial capital.

The fighting has sent some 200,000 civilians fleeing the northern city, according to the U.N., which warned of a looming humanitarian catastrophe, while France said it would call an urgent U.N. Security Council meeting on Syria.

Enjoyed the music-packed Olympics opening ceremony? Now you can buy the album — and thousands have.

The soundtrack album, which went on sale as a download minutes after Friday's ceremony ended, has topped the iTunes album chart in Britain, France, Belgium and Spain, and has reached No. 5 in the United States.

Metallica vocalist James Hetfield had warned things could get perilous at the start of the band's fifth tour of Mexico, saying "We're very focused on how dangerous this show is."

The audience of more than 22,000 believed it too. Many of the fans were visibly terrified Saturday night as the band re-enacted its burn-down-the-stage performance from 1998's "Cunning Stunts" video album.

Gunmen loyal to ousted Yemeni ruler Ali Abdullah Saleh on Sunday seized a security building near the Interior Ministry in the capital for a few hours before vacating it, a security official said.

The official said the gunmen were sent by a former security official and a relative of Saleh. After taking over the building in Sanaa, they blocked off the airport highway where it is located.

NBC's Bob Costas noted a controversy over honoring Israeli athletes killed at the Olympics 40 years ago during his coverage of the opening ceremony Friday but stopped short of offering his own protest.

The International Olympic Committee had declined a request to hold a moment of silence during the ceremony to acknowledge the 11 Israeli athletes and coaches killed by Palestinian gunman in Munich in 1972. Costas called that decision insensitive during an interview this month and indicated he would call for his own moment of silence when Israeli athletes marched into the Olympic Stadium Friday.

The producer of this year's Emmy Awards said it's a challenge to decide who to include in the ceremony's memorial tribute.

About three-dozen stars and other industry notables typically are honored in the "in memoriam" segment, although many more are deserving, executive producer Don Mischer said Friday.
