Russian president Vladimir Putin has completed his annexation of Crimea after signing a law making the Black Sea peninsula part of the Russian Federation.

Tensions remain high in Ukraine as Kiev debates whether to pull its troops from the Crimean peninsula, where Russian forces have seized Ukrainian ships and evicted soldiers from military bases. Crimeans have lined up eagerly to apply for Russian passports. Russia claimed that some Ukrainian troops had switched sides to join the Russian military.
