The LGBTQ community in Puerto Rico is especially vulnerable, right now.

More than a month after Hurricane Maria first hit Puerto Rico, San Juan's most popular gay club, Circo Bar, has been bombed by a group of masked assailants, according to the Puerto Rican newspaper El Vocero.

Circo had been operating on a generator when it was attacked Saturday night—reports indicate the weapon was a crude bomb called a Molotov cocktail, or flammable liquid lit inside a bottle. No one was reportedly harmed and no permanent damage was done to the bar. Police have yet to identify the perpetrators.

Puerto Rican activist Pedro Julio Serrano tweeted of the incident that officials need to “investigate if there is an angle of hatred,” noting homophobia was the likely cause.

Since Maria struck Puerto Rico, at least 51 have died and many more have been left without homes, water, electricity, and other vital resources.
