(Adds quote and detail paragraph 2 and 2) BISSAU, Dec 2 (Reuters) -

Guinea-Bissau's electoral commission said on Tuesday it is unable to finalize the November 23 presidential election after armed men seized ballots and vote tallies from its offices. Army officers in the West African state seized power on November 26, a day before the electoral commission was due to announce the results of the contested election.

"We are not in material and logistic conditions to follow (through with) the electoral process," Idrissa Djalo, a senior official of the electoral commission, said in a statement.
