What caused protests in Guinea in 2007?

In January 2007, an alliance of unions, political groups, and civilian societies organized protests in Guinea to challenge the high cost of living and widespread government corruption. The alliance also demanded the resignation of President Lansana Conté.12

These demonstrations were met with force by security services, resulting in the deaths of several protesters. Although the government declared a state of emergency in February, further unrest occurred in May 2007, when soldiers staged violent protests to demand better pay.12
