The Singapore Sand Smugglers

The causeway linking Singapore to the southern tip of the Malaysian peninsula is normally clogged with cars and trucks making the short international journey, but things got particularly bad on Feb. 1, when traffic came to a grinding halt. Thirty-seven trucks were abandoned where they stood on the Malaysian side, just yards away from a customs checkpoint, their drivers having simply walked away. Upon further investigation, it was discovered that they were carrying an illegal substance — but not drugs, illegal migrants, or precious jewels. They were carrying sand.
