Tunisian bus plunges off cliff, killing at least 24

At least 24 Tunisians were killed and 18 more injured when a bus plunged into a ravine on Sunday, in one of the country's worst road accidents.The bus had set off from Tunis to the picturesque northern mountain town of Ain Draham, a popular autumn destination for Tunisians near the Algerian border, the tourism ministry said.A sign reading in English "Sweet Time Travel" -- apparently the name of the travel agency that ferried the tourists from Tunis -- lay among the debris.
