Budget airline Ryanair says it has cancelled dozens of flights to and from destinations in Spain, Portugal and the Canary Islands.

The Oklahoma Department of Emergency Management said three people were killed at Tecumseh on Monday and that another person died at Oklahoma City. Tecumseh is about 45 miles southeast of Oklahoma City.
The agency did not have any additional details.
The storms caused traffic accidents that closed two major cross-country interstates. Damage was reported throughout much of northern, central and eastern Oklahoma.
The Storm Prediction Center at Norman had predicted the outbreak, saying the atmosphere had the right mix of winds, heat and moisture.

That's important to know, because the way BP caused devastation in Alaska is exactly the way BP is now sliming the entire Gulf Coast.
Tankers run aground, wells blow out, pipes burst. It shouldn't happen, but it does. And when it does, the name of the game is containment. Both in Alaska, when the Exxon Valdez grounded, and in the Gulf last week, when the Deepwater Horizon platform blew, it was British Petroleum that was charged with carrying out the Oil Spill Response Plans (OSRP), which the company itself drafted and filed with the government.
As a result of the degradation, the world is moving closer to several "tipping points" beyond which some ecosystems that play a part in natural processes such as climate or the food chain may be permanently damaged, a United Nations report said.
The third Global Biodiversity Outlook found that deforestation, pollution or overexploitation were damaging the productive capacity of the most vulnerable environments, including the Amazon rainforest, lakes and coral reefs.
"This report is saying that we are reaching the tipping point where the irreversible damage to the planet is going to be done unless we act urgently," Ahmed Djoghlaf, executive secretary of the UN Convention on Biological Diversity, told journalists.
Djoghlaf argued that extinction rates for some animal or plant species were at a historic high, up to 1,000 times those seen before, even affecting crops and livestock.
New Orleans, Louisanna -- With the impending threat of a growing oil slick just offshore, US Gulf coast states are seizing at all straws to avert disaster, with police in north Florida even suggesting protecting beaches with rolls of hay.
"That's why we get a lot of inventions in wartime, because people are willing to take a chance," Eric Smith, an oil and gas expert at Tulane University in New Orleans, said of the flood of ideas on how to stop the spill in the Gulf of Mexico.
On Florida's Santa Rosa Beach, Walton County Sheriff Michael A. Adkinson and C.W. Roberts, Inc., a private contractor, unveiled their audacious plan to stop oil from blackening 26 miles of pristine white beaches facing the Gulf.

The spill is spreading west, further from Florida but toward the important shipping channels and rich seafood areas of the Louisiana shoreline, where fishing, shrimping and oyster harvesting bans have been widened.
A state of emergency was declared in Lafourche Parish, Louisiana, with sheen, the leading edge of the oil slick, forecast to come ashore near Port Fourchon within days.
BP is exploring several new options to control the spill after a buildup of crystallized gas in the dome forced engineers to delay efforts to place a massive four-story containment chamber over the rupture on Saturday.
The dam of the Gedzhukh lake was not damaged, the source said on Tuesday. The republican emergency service and the republican authorities laid out an evacuation camp for 250 people, but the local residents prefer to stay temporarily at their relatives.
The Federal Emergency Management Agency has received 8,500 requests for financial aid, which could come in the form of loans or grants, FEMA Administrator Craig Fugate said in a conference call with reporters.
"This is a very large, very complex flood event and the numbers are only going to go up," Fugate said.
A weekend deluge triggered flash flooding and pushed rivers out of their banks in parts of Tennessee, Kentucky and Mississippi, killing some 30 people.
"I'd be astonished if there weren't $1 billion in damage in the private sector, and probably considerably more," Tennessee Governor Phil Bredesen told reporters.

Black waves of oil and brown whitecaps are seen off the side of the supply vessel Joe Griffin at the site of the Deepwater Horizon oil spill containment efforts in the Gulf of Mexico off the coast of Louisiana, Sunday, May 9, 2010.
The equipment to be offloaded from another vessel would use a tube to shoot mud and concrete directly into the well's blowout preventer, a process that could take two to three weeks. But BP PLC spokesman Mark Proegler said no decisions have been made on what step the company will take next.
The company was considering several options, including the technique known as a "top kill," Proegler said.
Crews planned to secure the big box about 1,600 feet from the massive leak site, much farther away from where it was placed Saturday after icelike crystals clogged the top when it was over the leak, according to a daily activity sheet reviewed by The Associated Press.
It could be at least a day before BP can make another attempt at putting a lid on a well spewing thousands of gallons of crude into the Gulf each day.
Waves of dark brown and black sludge crashed into a boat in the area above the leak. The fumes there were so intense that a crewmember of the Joe Griffin and an AP photographer on board had to wear respirators while outside.

A Blue Heron flies lazily across Marshall Lake beneath the snow-capped San Francisco Peaks on Thursday. After a winter of heavy snowfall, area lakes are at, or near, capacity.
But the finer fuels like grasses and twigs are beginning to dry, leading to the expectation of severe fires in grasslands and deserts at lower elevations. Depending on the weather and the wind, as seen last week in Timberline, the bigger fuels could dry, too.
"The future weather is what will determine whether it will be a moderate or severe fire season," said Buck Wickham, division chief of the Peaks Ranger District on the Coconino National Forest.
