Israel has deported 150 Sudanese migrants who entered the country illegally in search of work

They were flown out and were returning home via a third country, an Israeli official said. The UN refugee agency has confirmed the operation. Israel recently stepped up efforts to stop Africans from entering illegally across its southern border with Egypt. The Israeli official said some 200 Sudanese had been flown out of the country in recent months. The official said no further details were being given because of concern about the migrants' safety once they returned to Sudan. The Israeli government estimates that over the past five years, more than 30,000 Africans have entered illegally via the country's southern border. Israel says the migrants - from Sudan, Eritrea and other countries - come mainly in search of work, and are threatening local jobs. The government has been building a barrier along the Egyptian border to try to stop people from crossing it illegally, and it has also approved plans to set up a special facility to house those who are detained.
