Just days after the Argentine Congress postponed debate on a gay marriage bill, a fifth gay couple has married in the country's capital, the Argentine news agency Telam reported.

The gay rights group Federation Argentine of Lesbian, Gay, Bisexual & Trans – la Federacion Argentina de Lesbianas, Gays, Bisexuales y Trans (FALGBT) – announced the union of Alejandro Luna and Gilles Grall, a Frenchman, on Friday.

They are the fourth gay couple to marry in Buenos Aires so far. In December, two men – Alejandro Freyre and Jose Maria Di Bello – became the first gay couple to marry in Argentina. The couple married in the southern state of Tierra del Fuego after Governor Fabiana Rios issued a special decree. The wedding was originally scheduled to take place in Buenos Aires, but a national judge ordered a halt to the ceremony at the last minute, overruling a lower court's decision.

“Gilles Grall is a French citizen,” Maria Rachid, president of FALGBT, said in a statement, “so this marriage is unique in allowing the couple to continue their relationship, and only through marriage may Gilles obtain permanent residence and remain in Argentina with the person he loves and chose to share his life with.”

Grall, who met Luna during a 2008 business trip, said: “When you find love, anything is possible.”

On Wednesday, Argentina's Chamber of Deputies (la Camara de Diputados) failed to gain sufficient support to open debate on a gay marriage bill, but lawmakers say they'll hold a special session next Wednesday.

In announcing the Luna-Grall marriage, Rachid urged lawmakers to approve the gay marriage bill.

Recognition of gay unions is gaining ground in Latin America. Several Argentine cities, including its largest city of Buenos Aires, have approved civil unions for gay couples. In March, a gay marriage law took effect in Mexico City, making it the first municipality in the region to approve such unions. Uruguay recognizes gay and lesbian couples with civil unions.
