SANAA (AFP) - Key dates in Yemen since a transition accord was signed by the regime and the opposition in November 2011 calling for a national dialogue.
The accord, signed in Riyadh following an bloody 11-month Arab Spring-inspired uprising, resulted in president Ali Abdullah Saleh stepping down after 33 years in power and being replaced by his deputy, Abdrabuh Mansur Hadi.
- November 23: Saleh signs a deal with the parliamentary opposition, drawn up by Gulf monarchies, to transfer power to Hadi, in exchange for immunity from prosecution for him and his family.
The accord also provides for a national dialogue to draw up a new constitution and prepare for elections.
- February 25: Hadi is sworn in days after winning a presidential poll as the sole candidate. A suicide bombing, claimed by Al-Qaeda, kills 26 troops in the southeast.
- March 4: 185 soldiers and at least 25 suspected Al-Qaeda gunmen killed in the south.
- April 9-14: More than 220 killed in clashes between the army and Al-Qaeda.

- May 21: Some 100 soldiers are killed and hundreds wounded in a suicide bomber bombing in Sanaa claimed by Al-Qaeda.
- March 18: Launch of the national dialogue, sponsored by the UN and Gulf monarchies but boycotted by an alliance of groups demanding autonomy or independence for the south.
- January 25: Factions agree to draw up a new constitution and establish a federal state.

- August 4: Thousands of Huthi supporters take to Sanaa's streets demanding the government's replacement.
- September 18: Clashes erupt between the Huthi rebels and Sunni Islamists, backed by troops.
- September 21: Huthis seize the government headquarters and state radio and military sites in Sanaa, and Prime Minister Mohamed Basindawa resigns. More than 270 people are killed. Rival groups sign a UN-brokered peace deal, providing for a Huthi withdrawal from the capital and the formation of a new government.
- November 7: Yemen announces a new government, which is rejected by the Huthis.
- January 20: Huthis attack Hadi's residence and seize control of the presidential palace.
