The number of African infiltrators attempting to cross into Israel from Egypt has dropped sharply, according to figures released Sunday by the Prime Minister's Office.

According to the figures, since the start of September, 150 refugees crossed into Israel, as opposed to the 900 who came in July.

The PMO attributed the drop to an agreement signed between Prime Minister Ehud Olmert and Egyptian President Hosni Mubarak, in which the latter promised to prevent the infiltration of Africans into Israel, and to receive those who Israel would return.
