Hundreds of people marched through the capital of Puerto Rico to demand that the governor approve a constitutional amendment stating that only a marriage between a man and a woman is valid.
The protesters walked on April 13 from the U.S. territory's seaside Capitol building to the governor's mansion in historic Old San Juan.
It is the second such march in the past three months. A similar march in February drew an estimated 200,000 people.
The protest comes as legislators are holding hearings on legislation that would outlaw discrimination based on gender or sexual orientation and extend a domestic violence law to gay couples.
