Prime Minister Binyamin Netanyahu on Wednesday night ordered the Defense, Transportation and Interior ministries to draw up plans for a fence in order to stop infiltrators crossing the southern border.
The alternatives will be tested in small sections, and when the type of fence has been decided upon, it will be constructed in stages over several years.
Netanyahu issued the directive in a special meeting on the issue of foreign workers and the prevention of illegal infiltration into Israel.
It was also decided that within two weeks, plans will be presented for stricter law enforcement and punishments against those employing illegal workers.
Finance Minister Yuval Steinitz, Public Security Minister Yitzhak Aharonovich, Interior Minister Eli Yishai and Strategic Affairs Minister Moshe Ya'alon were among those attending discussions.
The meeting came days before the planned November 1 end of the moratorium on the deportation of foreign workers' children.
