Three rockets were fired at Baghdad's Green Zone, wounding seven security force personnel as parliament was holding its first session in two months, Iraq's security forces said. The parliament, at the centre of a months-long political paralysis, met for the first since deadly unrest in August to vote on the resignation of its speaker. (Photo by Ahmad Al-Rubaye/AFP Photo)

A boy jumps into a pool of mud during the traditional “Bloco da Lama” or “Mud Street” carnival party, in Paraty, Brazil, Saturday, February 25, 2017. Legend has it the “bloco” was born in 1986 after local teens hiking in a nearby mangrove forest smeared themselves with mud to discourage mosquitoes and then wandered through Paraty. The party grew year after year, but revelers eventually were banned from parading in the colonial downtown after shopkeepers complained pristine white walls were stained with the hard-to-remove mud.
