People walk on the streets during protests. Three weeks of protests that have rocked Bolivia led to President Mesa offering his resignation, for the second time this year, to congress. Blockades, protests and concentrations have brought the country to a standstill and confrontations between police and protestors happen daily.  At the center of the conflict is the indigenous movement's desire to nationalize gas and rewrite the constitution. Congress must now meet to decide of they will accept the president's resignation.
