JERUSALEM - Thousands of people demonstrated on Saturday in central Tel Aviv to protest against Israel's plan for the mass expulsion of Eritreans and Sudanese who entered the country illegally.

Israeli media said more than 20,000 people - migrants and Israelis - took part in the rally, with footage broadcast live on the Ynet news website showing them chanting: "We are all human beings."

"There is no difference between their blood and our blood," chanted the demonstrators.

Israel's supreme court earlier this month suspended the controversial government plan to deport thousands of Eritrean and Sudanese migrants in response to a challenge from those opposed to the move.

The court said in its decision the state was given until Monday to provide further information and the suspension on deporting them to a third country would remain in place until then.

The Israeli government says the migrants have to leave the country for an unnamed African destination in exchange for $3,500 and a plane ticket, or they will be incarcerated indefinitely.

Prime Minister Benjamin Netanyahu in January said migrants who entered illegally have the choice of leaving voluntarily or facing indefinite imprisonment with eventual forced expulsion.

On Tuesday, he said an electronic fence along the Israel-Egypt border has saved the Jewish state from "severe (jihadist) attacks ... and something much worse, a flood of illegal migrants from Africa".

The Interior Ministry says there are some 42,000 African migrants in Israel, mainly from Sudan and Eritrea.

Most of them began arriving in 2007, through the border with Egypt's Sinai Peninsula.
