SANAA – Yemeni president Ali Abdullah Saleh is scrambled to save his 32-year rule against growing popular protests demanding his ouster.
Though he still enjoys the support of the armed forces, the embattled leader has suffered growing defections in his army, ruling party and political elite.
Here is a timeline of Saleh’s rule of the Arabian Peninsula country provided by Reuters.
July 1978 - Saleh takes power in the former North Yemen.
Feb. 1979 - Saleh crushes an attempt to overthrow him.
May 1990 - Pro-Western North Yemen and socialist South Yemen merge after 300 years of separation to form a powerful new republic dominating the strategic entrance to the Red Sea. North Yemeni leader Saleh proclaims unification in Aden after the parliaments of both states elect him president.
May-July 1994 - Northern Yemen declares the Yemeni civil war is over after gaining control of Aden, its southern foe's last bastion and ending a bid to revive an independent state.
Sanaa declares that former vice-president Ali Salem al-Baidh and his supporters who tried to secede from a four-year merger with the north have been defeated in a two-month civil war and that unity for the Yemen is now assured. Southern leaders led by Baidh, who set up a breakaway southern state on May 21, are forced to flee into exile.
Oct. 2000 - Bombing of USS Cole in Aden harbour kills 17 sailors and blows hole in navy vessel's hull.
Nov. 2001 - Saleh declares support for Washington's "war on terror".
Feb. 2008 -- A fragile truce is signed with the Houthis, but clashes soon resume. Saleh has yet to crush the four-year-old Houthi revolt by Zaidi Shiite tribes in the northwest region of Saada. Saleh unilaterally declares the war over in July 2008. However, full-scale fighting resumes a year later.
Jan. 2009 – Al-Qaeda's Yemeni and Saudi wings announce merger in new group called al-Qaeda in the Arabian Peninsula (AQAP) led by Nasser al-Wahayshi.
Nov. 2009 - Saudi Arabia launches a military offensive against Houthi rebels after a rebel cross-border incursion. The Houthis deny accusations that infiltrators entered Saudi territory and call the offensive against the group "unjustified", accusing it of mainly targeting civilians.
Jan. 2010 - A meeting of Western and Gulf foreign ministers in London aims to bolster Yemen's fight against al-Qaeda.
Feb. 2010 - Yemen and northern Houthi rebels agree to a truce aimed at ending the war that has raged sporadically since 2004 and which has drawn in Saudi Arabia.
Feb. 2011 - Saleh says he will not seek to extend his presidency beyond his current term, which expires in 2013.
Feb. 3 - A day of anti-government protests attracts more than 20,000 people on to the streets in Sanaa.
March 2011 - The opposition presents Saleh on March 2 with a roadmap for a smooth transition of power, offering him a graceful exit.
Saleh, hoping to defuse increasingly violent protests, says he will draw up a new constitution to create a parliamentary system of government. An opposition spokesman swiftly rejects the proposal.
March 18 - Snipers kill 52 protesters among crowds that flocked to a sit-in at Sanaa University after Friday prayers. The killings prompt Saleh to declare a state of emergency for 30 days that restricts freedom of movement and the right to gather and gives police more powers to make arrests. The tourism minister and head of the ruling party's foreign affairs committee quit in protest.
March 20 - Saleh fires his government.
March 21 - General Ali Mohsen, a powerful figure close to Saleh, expresses support for pro-democracy protesters but stops short of resigning or demanding that Saleh end his rule. Abdel-Wahhab Tawaf, Yemen's ambassador to Syria, also resigns his post.
