Argentina's lower house of Congress approved a law early Wednesday that allows same-sex marriage, the government-run news agency reported.
The Chamber of Deputies passed the bill 126-109 with five abstentions, the Telam news agency said. The vote occurred at 2:45 a.m. after 12 hours of debate, Telam said.
The Argentinean Senate will have to pass the measure before it can become law. It's not clear when that vote will take place.
