Smugglers in Algeria have reportedly come up with a novel way to get their contraband into Morocco - donkeys, with tape recorders on their backs.

A taped message is repeated, saying "Err", Arabic for "walk", so that the donkeys do not stop as they follow the smugglers' tracks unaccompanied.

However, the customs service learnt of the ruse and has killed 200 of the donkeys, says the El Khabar newspaper.
