Sa'dah Insurgency (2004-Present)---In 2004, the Sa'dah Insurgency began in the northwestern tip of Yemen, with the Islamic cleric Hussein Badreddin al-Houthi, the leader of the Shiite Zaidiyyah sect, launched an uprising against the Yemeni government.
Following a bloody war which ended in 1932, the new kingdom of Saudi Arabia concluded a peace treaty with it's southern neighbor, Yemen. This agreement, called the Taif Treaty, delineated their common border, though disputes have flared up over the years. Apparently, the official reasons for this current round of border fighting relates to disputes over who owns certain islands in the Red Sea.
However, it is also known that the monarchist Kingdom of Saudi Arabia is rather uncomfortable with Yemen's experiment with democracy (Yemen is the only nation on the Arabian Peninsula with a democratic style government). Allegations have been made that Saudi Arabia is attempting to sabotage this democratic regime through military intimidation as well as aiding internal strife within Yemen.
