The management of Nigeria's new Museum of West African Arts (MOWAA) do not know when it will open after an armed gang stormed the building during a preview event on Sunday.
Benin City's multimillion-dollar museum, designed by architect David Adjaye and run by director Phillip Ihenacho, was due to open yesterday but the doors have stayed shut.
A museum spokeswoman told HENI News: "We do not currently have a confirmed opening date for the museum; it will be announced in due course."
Its inaugural exhibition, curated by Aindrea Emelife, is an updated version of Nigeria's pavilion at last year's Venice Biennale and features works by eight international artists with Nigerian roots including Precious Okoyomon and Yinka Shonibare.
Sunday's attack, which saw guests escorted off the site by security, was reportedly sparked by an ongoing argument over the future of the famed Benin Bronzes which were looted by the British in 1897.
The museum was originally billed as a home for any artifacts that were returned but that changed after a descendant of the King who originally owned them objected and revealed plans to put them on show in a separate museum.
MOWAA has been accused by the king's supporters of securing donations on the basis it would show the bronzes - money they say should go to the royal museum.
