Should the sub-Saharan African and Egyptian artifacts in the Louvre be returned to Africa?

Question

Isn't it true that the Louvre and The British Museum have many artifacts from Africa/Asia/South America etc.? Do they have a right to keep these artifacts, or should they be returned to the countries where they came from?
After all, if the Greeks have been demanding that the Elgin Marbles be returned, doesn't Africa have even more of a right to have their artifacts, which may have been taken during colonization, returned?
Were these artifacts, in fact, stolen?
Isn't there a growing movement in this direction where it is becoming more fashionable to admit that it is wrong for Western Museums to keep such items?
