Two buses have collided on a main road in Morocco, killing 25 people and injuring 62 others, say officials. Eleven of those hurt are in a serious condition, BBC quoted Morocco's national news agency as saying. Moroccan officials said excessive speed appeared to be a factor in the crash. The accident took place on Tuesday morning some 20 km (15 miles) from the tourist town of Marrakech on the road to Agadir.
