A wave of protests has been sweeping across Colombia since 28 April. By 31 May, 59 people had died. Protesters block key roads, causing shortages of fuel and food, and there have been violent clashes between the security forces and demonstrators. The government is holding talks with protest leaders, but with more and more groups joining in the demonstrations a quick resolution seems unlikely. When the protests started the main call was for tax reforms. Four days later the bill was withdrawn. Human rights groups reported that riot police had used tear gas and in some cases shot live ammunition to stop the protests. So rather than abating after the cancellation of the tax reform, the protests intensified. Over 2,300 civilians and members of the security forces have been injured. There have also been marches by thousands of Colombians opposing the roadblocks, causing more violent clashes.
