A man carrying an axe walks past a house marked with bullet holes in Gyallesu district after recent clashes between Shi'ites and the army in Zaria, Kaduna state, Nigeria, February 3, 2016. Sectarian tensions are rising in Nigeria's Muslim north, where hundreds of Shi'ites were killed in clashes with the army in the town of Zaria in December, according to Shi'ites and rights groups. Following the clashes, bulldozers sent by the state levelled Shi'ite shrines, a cemetery and offices in the deeply divided town. The region is already grappling with an insurgency waged by the jihadist Boko Haram group. (Photo by Afolabi Sotunde/Reuters)

Limassol's long-established parade is Cyprus' biggest and most famous, drawing revelers from across the east Mediterranean island. This year's parade drew huge crowds as people sought lighthearted reprieve from the bailed-out country's recession. The parade marks the start of the 40-day fasting period of Lent in the run-up to the Orthodox Christian Easter. (Photo by Petros Karadjias/AP Photo)
