Airports across the United States on high alert

Washington: Airports across the US are on high alert after two parcel bombs heading for the US from Yemen were intercepted in Britain and Dubai.

Both parcels contained an explosive called PETN. It is the same material used in the Christmas Day and shoe bomb attempts. The discoveries have prompted US authorities to screen cargo planes more thoroughly and tighten security at all US airports. US President Barack Obama has called this a 'credible terrorist threat'. The involvement of the Al Qaeda is being probed.

One of the suspicious packages was found at East Midlands Airport, about 160 miles north of London. The other was discovered at a FedEx Corp facility in Dubai.



Security officials in Britain and Dubai intercepted parcel bombs being sent from Yemen to the United States in a "credible terrorist threat," Obama said on Friday.

He said the parcels were bound for "two places of Jewish worship in Chicago."

Suspicion fell on Al Qaeda in the Arabian Peninsula, based in Yemen, which took responsibility for a failed plot to blow up a US passenger jet on Christmas Day in 2009.

"Initial examinations of those packages has determined that they do apparently contain explosive material," Obama told reporters in a televised briefing, calling it "a credible terrorist threat against our country."

The White House said earlier that "both of these packages originated from Yemen" and that Obama was notified of the threat on Thursday night.

One of the suspicious packages was found on a United Parcel Service cargo plane at East Midlands Airport, about 160 miles north of London. The other was discovered at a FedEx Corp facility in Dubai.

"As an additional safety measure, FedEx has embargoed all shipments originating from Yemen," said Maury Lane, a spokesman for the world's largest cargo airline. "The package never was on a FedEx aircraft. We don't fly to Yemen."

British police said an item found on the UPS plane was sent for further testing. CNN said it was an ink toner cartridge converted into a bomb.

Before Obama spoke, an FBI source had said that initial tests in Britain revealed no explosives.

An official source in the United Arab Emirates said, "An explosive device was found in the package that originated in Yemen" and that the parcel was similar to the one found in Britain.

In the United States, UPS planes were checked in New Jersey and Philadelphia. The Transportation Security Administration said they were searched "out of an abundance of caution."

Some analysts and US officials speculated that the suspicious parcels may have been a test of cargo screening procedures and the reaction of security officials.

"One possibility, if this is terrorism related, is that this may be a trial run," one US official said.

Intelligence about the possible plot had come from an ally abroad, the official said, without elaborating.

The US Department of Homeland Security said it was stepping up aviation security measures as a result of the scare. The British government said it was "too soon to say" whether it would follow suit but was "urgently considering" what steps to take about freight coming from Yemen.

The man accused of the failed Christmas Day bombing, Umar Farouk Abdulmutallab, has told US investigators he got the device and training from Al Qaeda militants in Yemen.
