Britain has banned passengers from carrying toner cartridges on airplanes in the wake of last week's terrorism scare involving explosive devices shipped from Yemen.

"From midnight tonight we will suspend the carriage of toner cartridges larger than 500 grams in passengers' hand baggage on flights departing from U.K. airports," Theresa May told the British House of Commons on Monday.

The move comes in the wake of last week's discovery of U.S.-bound packages in Dubai and Britain that originated from Yemen.

May also noted that a ban on unaccompanied air freight bound from Yemen into the U.K. would also be extended to packages of Somalian origin. Germany has already banned all flights of Yemeni origin from landing in any of its airports.
