USS Cole bombing in Aden

Armed conflict broke out between forces aligned with the government in Sana’a and southern leaders amid unresolved unification disputes.

Southern leaders proclaimed the Democratic Republic of Yemen during the civil war; international recognition did not follow.

Northern-led government forces captured Aden, ending the principal military phase of the 1994 civil war and entrenching grievances over southern exclusion.

Elections strengthened President Ali Abdullah Saleh’s General People’s Congress as major southern opposition forces remained marginalized.

Ali Abdullah Saleh won Yemen’s first direct presidential election in a contest with limited meaningful competition.

The attacks in the United States intensified American counterterrorism cooperation with Yemen and pressure on the Saleh government.

A US missile strike killed suspected al-Qaeda operative Qaed Salim Sinan al-Harethi and five others; the operation raised sovereignty and accountability questions.

The General People’s Congress maintained its parliamentary dominance amid opposition concerns over unequal political competition.

Fighting began between government forces and followers of Hussein Badreddin al-Houthi, laying the foundation for successive wars in northern Yemen.

Government forces killed Hussein Badreddin al-Houthi; the movement persisted and later reorganized under other leaders.
