TIMELINE-Key events since 2006 Hamas election victory

(Reuters) - Palestinian President Mahmoud Abbas swore in an emergency cabinet on Sunday formed after he dissolved a three-month-old Hamas-led unity government.

Oct 1 - Worst internal Palestinian fighting in a decade raises fears of civil war.

Nov 26 - Ceasefire in Gaza announced, ending five-month Israeli offensive that followed abduction of Shalit, who remains held by militants.

Nov 30 - Abbas says continued unity talks at a “dead end”.
