Violence broke out as several hundred people demonstrated in Tel Aviv on Wednesday night against the sizeable community of African immigrants in the city, police spokeswoman Luba Samri said.
"Following the violence, we arrested five demonstrators," Samri added.
The media reported that people shouted xenophobic slogans, such as "blacks out," and chided the "bleeding heart leftists" who defend immigrants.

Over the years, an estimated 60,000 Africans, mostly from Sudan and Eritrea, have slipped over the border into Israel from Egypt.
