KABUL (Reuters) - Afghanistan's rival presidential candidates have agreed in writing to work together to form a government of national unity, both candidates told a news conference, following meetings with U.S. Secretary of State John Kerry on Friday.

A joint declaration signed by both candidates, a copy of which was obtained by Reuters, did not provide details on the government framework, except to say that both sides would form commissions to work on its structure.
