Magen David Adom said that at least 10 people were injured, three moderately to seriously.
Police confirmed that the explosion was a terrorist attack, although Channel 2 reported that it was not a suicide bombing and thus police were searching the area for additional explosive devises.
Channel 2 reported that police arrested a suspect near the Ramat Gan diamond exchange, who they believe may be carrying an explosive device. Police believe a female terrorist may still be at large in the area, armed with explosives.
