The UK banned unaccompanied freight from Somalia, extending after Nov. 1 a ban on such freight from Yemen following the discovery of parcel bombs at airports in Britain and Dubai.
The ban, which comes into force at midnight, is a "precautionary measure" based on possible contact between al Qaeda in Yemen and Somali terrorist groups and concern over security at Mogadishu airport, Interior Minister Theresa May told Parliament.
Printer toner cartridges weighing more than 500 grams will also be banned from hand baggage on all passenger flights from the UK, May said.
In addition, only designated firms approved by the Department of Transport will be able to import toner cartridges above 500 grams.
The explosive devices discovered in the UK and Dubai were concealed in printer cartridges.
May said there is no information another attack is imminent but the government has begun a review of all aspects of air cargo security.
Earlier, the government's emergency planning committee, called Cobra, met for the third time since the discovery on Friday of a parcel bomb on a U.S.-bound UPS aircraft at East Midlands airport 100 miles north of London.
Germany Monday suspended direct passenger flights to and from Yemen until further notice. It banned unaccompanied freight from Yemen over the weekend.
