Stop the violence against Sudanese peaceful protests

Since the end of December 18; Sudanese in cities all over the country started peaceful demonstrations due to the economic hardship they living (no fuel; bread and can't get money from their bank accounts) soon they start to demonstrate aginst the dictatorship regime that have been ruling for the last 29+ years and always make the same promises in similar situations in the past without any success..
During these on going demonstrations the regime forces and armed militias has used tear gas and live ammunition killing over 40 people; injured hundreds; detained and tortured too many; they even tear gased hospitals in violation to human rights and Sudan constitution which allow such demonstrations..
We want the Canadian minister of foriegn affairs to question the Sudanese ambassador in Ottawa about this excessive force.
