Authorities are investigating Nazi swastikas painted on two Florida synagogues this week, local media reports said Tuesday.
In the latest incident, a swastika, the initials "KKK" and a skull and bones were painted on a poster at the entrance to the Temple Emanu-El in Miami Beach.
"This is a serious situation," Barbara Breslow, the temple's director, told WSVN television. "Everybody is very concerned."
A surveillance camera recorded images of a possible suspect, a man with a backpack, at the synagogue's entrance at 3:00 am, the report said.
On Monday, another swastika and the name of the Islamist Hamas movement were painted on the exterior walls of a synagogue in western Miami.
That incident was reminiscent of yet another at a third synagogue at the end of July, when Israel was engaged in an offensive in Gaza against Hamas.
In that case, vandals spray-painted a red swastika and "Hamas" on the synagogue in Miami Beach.
