Disagreement delays end of Zimbabwe summit-source

LUSAKA, April 13 (Reuters) - The conclusion of a summit of southern African leaders on Zimbabwe's election stalemate was delayed by disagreement over the use of the word "crisis" in a final communique, a senior Zambian official said on Sunday.

"The delay to conclude the meeting has been caused by a disagreement on how the final communique should be phrased. Some leaders feel that including the word crisis will be inappropriate while others say the extraordinary conference in itself shows there is a crisis in Zimbabwe," said the official, who asked not to be named.

Before the summit started, South African President Thabo Mbeki said there was no crisis over the elections in Zimbabwe.
