Egypt's parliament authorised the deployment of troops outside the country after the president threatened military action against Turkish-backed forces in neighbouring Libya.
The parliament unanimously approved "the deployment of members of the Egyptian armed forces on combat missions outside Egypt's borders to defend Egyptian national security ... against criminal armed militias and foreign terrorist elements", it said in a statement.
The deployment would be made on a "western front" - a likely reference to western neighbour Libya. The move could bring Egypt and Turkey - which support rival sides in Libya's chaotic proxy war - into direct confrontation.
Egypt's House of Representatives, packed with supporters of President Abdel Fattah el-Sisi, approved the plan after a closed-door session on Monday.
Stephanie Williams, acting head of the UN support mission in Libya, on Monday called for an "immediate ceasefire ... to spare the 125,000 civilians who remain in harm's way and for an end to the blatant violations of the UN arms embargo".
Her comments came following her meeting on Sunday with the president of neighbouring Algeria, Abdelmadjid Tebboune.
