The New York Times story, by Katrin Bennhold, is horrifying. It begins:
LONDON — The two young volunteers from London had been briefed on how to dress respectfully. They had been warned not to wear anything provocative while teaching on the island of Zanzibar during the month of Ramadan.
So when the volunteers, Kirstie Trup and Katie Gee, both 18, strolled into Stone Town to get dinner last Wednesday, those who know them said they covered up despite the heat. The two men who rode up behind them on a moped gave no reason for targeting them — the men stopped, smiled and then doused the young women in acid, severely burning their faces, chests and hands, before speeding away.
Nothing to say, except read the whole story.
