Rioters in Aleppo in 1947 burned the city's Jewish quarter and killed 75 people.[44] In 1948, there were approximately 30,000 Jews in Syria. The Syrian government placed severe restrictions on the Jewish community, including on emigration. Over the next decades, many Jews managed to escape, and the work of supporters, particularly Judy Feld Carr,[45] in smuggling Jews out of Syria, and bringing their plight to the attention of the world, raised awareness of their situation. Following the Madrid Conference of 1991 the United States put pressure on the Syrian government to ease its restrictions on Jews, and on Passover in 1992, the government of Syria began granting exit visas to Jews on condition that they do not emigrate to Israel. At that time, the country had several thousand Jews; today, under a hundred remain. The rest of the Jewish community have emigrated, mostly to the United States and Israel. There is a large and vibrant Syrian Jewish community in South Brooklyn, New York. In 2004, the Syrian government attempted to establish better relations with the emigrants, and 12 Syrian-Jews visited Syria.
