Israel is expelling 150 more South Sudanese as part of its campaign to reduce the number of African migrants who have slipped illegally into the Jewish state.
Authorities are offering the migrants cash to leave voluntarily and threatening them with arrest if they do not.
Sabine Haddad, an interior ministry spokeswoman, said the latest flight with the expelled migrants was due to leave at midnight last night.
Some 60,000 Africans, mostly from Eritrea and Sudan, have slipped into Israel from Egypt since 2005 – most of them have fled repressive regimes and Israel cannot expel them.
Street violence against the migrants has surged in recent months, with businesses being targeted and attacked by gangs.
