Paris, France:
France on Friday boosted passenger screening at its airports, responding to a Washington request for extra security for US-bound flights over fears Islamist radicals could be plotting new attacks using hard-to-detect bombs.
The French move, announced by the DGAC civil aviation authority, follows similar action by Britain, and notably impacts Europe's two busiest hubs: Heathrow and Charles de Gaulle.
Combined, an average 2.5 million passengers use those two airports each day.
French and British authorities urged passengers to allow extra time to get past the additional measures, which were not specified but were believed to focus on footwear and electronic items such as mobile phones and computers.
US officials on Wednesday publicly demanded enhanced security for airports in Europe and the Middle East which have direct US flights. They did not say whether they had intelligence about a specific plot, but their actions suggested alarm.
The request was "based on real-time intelligence," according to a Homeland Security Department official who spoke on condition of anonymity.
On Thursday, the US embassy in Uganda warned of a possible plot targeting Entebbe airport serving the capital Kampala for later that day. But the danger period elapsed without incident.
- Danger posed by Al-Qaeda group -
Western intelligence services are concerned that hundreds of Islamist radicals travelling from Europe to fight in the Middle East could pose a security risk on their return. Most European passport-holders do not need a visa to travel to the United States.
One of the radical organisations, Al-Qaeda in the Arabian Peninsula (AQAP), is of particular concern.
US and other intelligence services believe AQAP is passing on sophisticated bombmaking expertise to militants fighting in Syria for use against Western targets -- most prominently, passenger aircraft.
"We have a long-standing concern of terrorist groups in trying to get undetected material on the planes," a US intelligence official told AFP.
AQAP "is always the group we think about when we talk about undetectable bombs," the official added.
Brooke Rogers of the War Studies Department at King's College London said that for extremist groups, bringing down an aircraft was the "ultimate prize -- if the attackers succeed, it will be spectacular for them".
And "unfortunately in aviation, it doesn't take a big amount (of explosives) to make a boom," said US airplane security expert Jeff Price.
- Era of airport screening -
France's aviation authorities said in a statement its new security measures "will be carried out in a way to limit as much as possible inconvenience to passengers, however delays are possible".
The stepped-up screening is taking place at Charles de Gaulle airport -- which has 47 US-bound flights a day at this time of the year -- and other airports in mainland France, as well as in far-flung French territories such as Tahiti.
A DGAC spokesman told AFP that "we cannot divulge the added measures" being taken.
However, Belgian Interior Minister Joelle Milquet, whose country is also stepping up airport security, told RTL-TVI on Thursday the measures would focus on electronic equipment such as tablets, computers and mobile phones "to make sure there are no explosives".
Britain downplayed the extra delays passengers would face, with Prime Minister David Cameron saying: "The safety of the travelling public must come first -- we mustn't take any risks."
His office said there was an "evolving threat" but declined to provide further details.
Although it implemented the additional security from Thursday, Britain was keeping its international terror threat level unchanged at substantial, the third highest grade out of five, where it has been since July 2011.
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 US-bound flight in 2001.
Experts say that if anyone could be behind the threat of a new generation of bombs, it was Ibrahim al-Asiri, a 32-year-old Saudi believed to be hiding out with AQAP in Yemen's restive southern provinces.
The terror alert in Uganda further rattled nerves, but it was not immediately clear if it was linked to the airport security boost.
Airport security across the world was greatly reinforced in the wake of the September 11, 2001 attacks in the United States.
It was further tightened after the shoe-bomber plot, and when another attempt to blow up "liquid bombs" on transatlantic flights was uncovered in 2006.
A previous high-profile attempt by AQAP to blow up a US-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.
