ZAMBIA · POST-ELECTION CRISIS

Key Facts

—The surrender: Brian Mundubile, runner-up in Zambia’s 13 August presidential election, surrendered to police on Thursday after about two weeks in hiding, much of it under United Nations protection in Lusaka.

—The allegations: Police are questioning him and running mate Makebi Zulu over “alarming activities” they say could threaten national security. Some Zambian outlets report detectives recorded formal statements linked to possible treason allegations; no charge had been announced as of the latest reports on Friday.

—The election: The electoral commission declared President Hakainde Hichilema re-elected with about 61 percent of the vote. Mundubile won roughly 38 percent and disputes the result.
