People in Yemen are due to elect a new president, ending current leader Ali Abdullah Saleh’s 33-year-rule.
Voters are expected to rubber-stamp Vice-President Abdrabbuh Mansour Hadi – the only candidate in Tuesday’s poll.
It comes after a year of violent anti-government protests in the Arabian peninsula’s poorest country.
Violence continued on Monday, with at least one polling station reportedly attacked in the south. One person is said to have been killed.
