Gay rights activist cheer after a session at the city's assembly in Mexico City December 21, 2009. Mexico City's assembly voted to extend gay couples full marriage rights on Monday in a landmark law that is the first of its kind in Latin America, a traditionally macho and Catholic region. The bill takes a 2006 law allowing civil unions by allowing gay couples to access family social security benefits and apply for joint credits as if they were a straight couple. [Xinhua/AFP Photo]
