U.S. terror warning puts airports worldwide on alert

Uganda may be center of plot to attack travelers, embassy says

United States-bound travelers from Europe and the Middle East faced tighter security at airports Thursday over fears that Al-Qaida-linked militants are developing new explosives that could be slipped onto planes undetected.

The stepped-up checks were ordered as the U.S. Embassy in Uganda warned of a “specific threat” to attack Kampala’s Entebbe International Airport between 9 p.m. and 11 p.m.

The new checks focused on electronic items such as laptops and mobiles, fueling fears that extremists such as al-Qaida could use them as their latest tactic in a long campaign of attacks involving aircraft.

U.S. Homeland Security Secretary Jeh Johnson announced the extra security on direct flights to the United States from some overseas airports on Wednesday, without citing evidence of any specific plot.

The move comes amid broader Western intelligence concerns that hundreds of Islamist radicals traveling from Europe to fight in the Middle East could pose a security risk on their return.

On Sunday, U.S. President Barack Obama warned that “battle-hardened” Europeans who embrace violent jihad in Syria and Iraq threaten the United States because their passports mean they can enter without a visa.

The airports concerned are located in the Middle East and Europe and were targeted “based on real-time intelligence,” said a Homeland Security Department official who spoke on condition of anonymity.

Britain confirmed it was bolstering security at its airports in response.

Belgian Interior Minister Joelle Milquet, whose country is also stepping up airport security, told a local broadcaster the measures would focus on electronic equipment such as tablets, computers and mobile phones “to make sure there are no explosives.”

“We have a long-standing concern of terrorist groups in trying to get undetected material on the planes,” a U.S. intelligence official said.

Al-Qaida in the Arabian Peninsula (AQAP) “is always the group we think about when we talk about undetectable bombs,” the official added.

A second U.S. government official noted that there was also “concern about groups that associate with one another and obviously enhance the threat environment.”

There are concerns AQAP is passing on bomb making expertise to militants fighting in Syria and that extremists with European passports could then bring these skills back home with them and launch an attack.

Brooke Rogers of the War Studies Department at King’s College London said that for extremist groups, bringing down an aircraft is the “ultimate prize — if the attackers succeed, it will be spectacular for them.”

And “unfortunately in aviation, it doesn’t take a big amount to make a boom,” said U.S. airplane security expert Jeff Price.

Experts say that if anyone could be behind the threat, it was Ibrahim al-Asiri, a 32-year-old Saudi believed to be hiding out with AQAP in Yemen’s restive southern provinces.

The terrorism alert in Uganda further rattled nerves, but it was not immediately clear if it was linked to the airport security boost.

Although the U.S. Embassy did not name any group, al-Shabab insurgents linked to al-Qaida have claimed attacks in neighboring Kenya, including the Westgate mall bloodbath, and Djibouti, as well as at home in Somalia.

Despite the increased checks, Britain said the international terrorism threat level issued by its domestic security service remained unchanged, at “substantial,” the third-highest grade of five, where it has stayed since July 2011.

Prime Minister David Cameron said Britain was taking a “safety first” approach.

“This is something we’ve discussed with the Americans, and what we have done is put in place some extra precautions and extra checks,” he told television channels.

“The safety of the traveling public must come first — we mustn’t take any risks.”

A spokesman for the prime minister said there was an “evolving threat” but declined to provide further details.

Officials insist passengers should not face significant delays, and London’s Heathrow airport — one of the world’s busiest international air hubs — and Gatwick, south of the capital, were both operating normally.

Passengers in Britain have long faced tight security measures at airports following high-profile threats, including a failed attempt by British “shoe bomber” Richard Reid to blow up a U.S.-bound flight in 2001.

Security was further tightened after a plot to blow up liquid bombs on trans-Atlantic flights was uncovered in 2006.

A previous high-profile attempt by AQAP to blow up a U.S.-bound plane failed on December 25, 2009, when Nigerian Umar Farouk Abdulmutallab tried to detonate explosives hidden in his underwear.

The Detroit “underwear bomber” is now serving a life sentence in the United States.
