Travelers using Denver International Airport’s free Wi-Fi service cannot visit Internet sites that airport officials consider provocative.

A report in The Denver Post says the airport is blocking Vanity Fair magazine’s Web site, the hipster site boingboing.net and others.

Airport spokesman Chuck Cannon says officials decided to block access to potentially racy sites when the airport made its wireless internet service free in November.

Cannon says the airport would rather deal with infrequent complaints about access than handle angry parents whose children might see pornography.

Critics say the airport is using the same technology used by repressive regimes in Sudan and Kuwait.

Andrei Lugovoi, named by Britain as a suspect in the killing of the former Russian agent Alexander Litvinenko in London, today claimed the UK’s special services tried to recruit him.

At a press conference in Moscow, which he organised, Mr Lugovoi repeated his denials of involvement in Litvinenko’s death.

British special services “asked me to collect compromising information on [the Russian] President [Vladimir] Putin”, he said, according to a translation by the Russia Today television channel.

“Litvinenko was not my enemy,” Mr Lugovoi, a former KGB bodyguard who is now a businessman, added. “I will fight to clear my name.”

Earlier this week, the British ambassador to Moscow delivered a request for his extradition. The Crown Prosecution Service last week said there was enough evidence to charge him with Litvinenko’s murder.

Litvinenko, a vehement critic of Mr Putin, died on November 23 last year. He had been poisoned with the radioactive isotope polonium-210.

Oil prices moved to a new record on Wednesday after the OPEC cartel decided to keep its production unchanged, ignoring calls from Bush to pump more oil into an ailing economy.

OPEC rebuffed its top consumer, arguing that the world was well supplied with oil and blaming financial speculators and mismanagement of the United States economy for the current high prices.

But the Organization of the Petroleum Exporting Countries was not completely oblivious to the political and economic impact of $100 oil. The sharp surge in prices recently has deterred the groups ministers from cutting their production, a move they seriously contemplated a few weeks ago to offset a seasonal slowdown in global oil demand in the second quarter.

With the United States economy slowing down, oil prices have risen sharply as investors seek refuge in commodities like oil and other hard assets to offset the drop in the value of the dollar and hedge against inflation.

Oil prices reached a new record on Wednesday, rising to $103.98 a barrel in midday trading on the New York Mercantile Exchange, up $4.46 on the day. The spike came after United States fuel inventories unexpectedly declined while tensions escalated between Venezuela, an OPEC member, and Colombia.

As prices have risen in recent years, relations between energy producers and their consumers have been increasingly acrimonious. Oil producers are seeking better terms for their dealings with foreign oil companies, and often restricting access to investments. OPEC ministers are also increasingly confident in their ability to prevent prices from falling below $80 a barrel.

As a sign of growing impatience with oil producers, Bush said on Tuesday that it would be a “mistake” for OPEC not to increase supplies. As the oil group was meeting in Vienna, the president repeated his assault on Wednesday, saying it was “obvious” that demand was stripping supplies, and pushing up prices.

“Americas got to change its habits; weve got to get off oil,” Bush said at a conference on renewable fuels. “Until we change our habits, theres going to be more dependency on oil.”

Chakib Khelil, OPECs president this year, said the high price of oil was not due to a lack of supplies. Instead, he cited the “mismanagement of the U.S. economy” and blamed financial speculators for driving up prices.

“If the prices are high, definitely they are not due to a lack of crude,” Khelil said in Vienna. “They are due to whats happening in the U.S.”

He added: “There is sufficient supply. Theres plenty of oil there.”

Most energy analysts agree there is no physical shortage of oil today. Commercial oil inventories are at relatively high level and that refiners are not lacking oil.

Ali al-Naimi, Saudi Arabias oil minister, said in Vienna that there was no need to increase supplies by “even one barrel of oil.” He said the reason behind Wednesdays soaring oil prices was “tremendous speculation.”

“There are even those who buy futures and speculate that oil prices will reach more than $200 in 2013 and 2015,” Naimi said in Vienna. “The most important thing that OPEC and Saudi Arabia look at is the stability of market factors.”

Still, OPEC recognized the threat posed by a slowing economy on its business.

“In reviewing the prospects for the oil market, the conference highlighted the economic slowdown in the U.S.A., which, together with the deepening credit crisis in financial markets, is increasing the downside risks for world economic growth and, consequently, demand for crude oil,” OPEC said in its final statement.

The oil cartel, which is next scheduled to meet in September, indicated it might call for an emergency meeting before then to review the market situation in the spring.

Meanwhile, ExxonMobil, Americas top oil company, plans a significant increase in its capital spending on new oil and gas projects in coming years as costs increase across the industry and rising political constraints mean oil companies are finding it increasingly challenging to pump oil out of the ground.

The high price environment is making it more difficult for companies like Exxon to expand its production and replace reserves, while posing a threat to global growth at a time the United States economy is slowing.

“Clearly the persistent higher cost that everyone is facing is now making its way into the next trench of projects,” Rex Tillerson, the companys chairman and chief executive, said at the companys annual analyst meeting in New York. “The costs are a significant challenge for the industry as a whole and they are a challenge to us as well.”
