Gunmen killed an Egyptian in Libya's eastern city of Benghazi on Tuesday, a medic said.
Ali Mohamed Hassan, a worker, was shot dead by unknown assailants in the city, the source told the independent Al-Wasat news website, adding that a post-mortem examination of the body was under way.
Egyptian authorities have repeatedly voiced alarm over violence against its citizens in Libya and warned against travelling to the North African nation amid an upsurge in militant attacks since the 2011 revolution that ousted autocrat Muammar Gaddafi.
Hundreds of thousands of Egyptians work in Libya, mostly as labourers, but the number has sharply diminished three years after the uprising.
Libyan authorities have struggled to hold back brigades of former rebels and Islamist militias who helped topple Gaddafi and have easy access to weaponry.
Car bombings and assassinations of soldiers and police officers have become commonplace in Benghazi, Libya's second largest city.
Several foreigners have also been killed in recent months by militiamen and Islamist militants
In February, seven Egyptian Christians were shot dead execution-style on a beach near Benghazi, a hotbed of Islamist militancy.
A month earlier, five Egyptian diplomats were kidnapped in the capital Tripoli in retaliation for Egypt's arrest of a Libyan militia chief, but were freed days later
Many foreign consulates have closed down in Benghazi and some airlines have stopped flights there since a militant onslaught in September 2012 killed the US ambassador and three other Americans.
