UN envoy Ibrahim Gambari called for the release of all political prisoners in Myanmar, including democracy icon Aung San Suu Kyi. President George W. Bush had previously warned that the US would pursue international sanctions against Myanmar's military regime if they failed to release detainees. The monk hood in Myanmar led peaceful protests against fuel hikes and deteriorating economic conditions, which grew into tens of thousands demonstrating against the military rule, but the junta cracked down violently in late September, killing and imprisoning many. The mass protests demonstrated a widespread consensus for transferring power from the military to a civilian government.
