JERUSALEM — After years of living on the margins of Israeli society, thousands of African asylum seekers flooded the streets of central Tel Aviv for a second day on Monday to protest their treatment by the Israeli authorities and to demand recognition as refugees.

Throngs marched to the United States Embassy on the Tel Aviv seafront, and delegations fanned out to the British, Canadian, French and Italian Embassies as well as the offices of the United Nations refugee agency, among others, to appeal for international attention and help.

On Sunday, tens of thousands demonstrated in Rabin Square in Tel Aviv, many chanting, “Freedom.” The migrants also began a three-day strike, leaving many restaurants and hotels without dishwashers and cleaners.

Although the concentrations of African migrants in the run-down neighborhoods of south Tel Aviv have caused friction with the local population, some celebrity chefs and cafe owners have come out in support of their striking workers, serving customers meals on paper plates.
