Egypt's army arrested 151 illegal migrants for attempting to cross to Libya through Marsa Matrouh governorate in Egypt's north west - 145 Egyptians and six Sudanese - state news agency MENA reported.
At least 500 illegal migrants have been arrested while attempting to cross to Libya since July.
Despite growing unrest since the toppling of longtime autocrat Muammar Gaddafi, Libya is still a destination for Egyptian migrant workers, mostly due to geographical proximity and the low cost of travel documents.
In a September report, the International Organisation for Migration estimated that up to one million Egyptians remain in Libya — predominantly from rural areas and Lower Egypt — meaning almost 16 percent of a total population in Libya of 6.2 million.
Egypt's Ministry of Manpower and Migration, however, puts the number at a tenth of that figure.
