M’BATTO, Ivory Coast (Reuters) - Before last month’s presidential election, M’Batto in central Ivory Coast was a small, peaceful town where ethnic groups intermarried and churches and mosques existed side by side without friction, residents say.Two weeks on and the streets are littered with empty shotgun cartridges, shops have been burned down and at least six people are dead, killed in ethnic clashes that some fear could herald a repeat of Ivory Coast’s civil wars in 2002 and 2010-2011. The Oct. 31 election, which was boycotted by the opposition, opened up old wounds around the question of identity in Ivory Coast between mostly northern Dioula migrants and the Agni southerners who see themselves as original settlers. The landslide win of President Alassane Ouattara for a controversial third term made tensions worse.
