EU border agency Frontex said Tuesday it had started to deploy 293 officers and 15 vessels on Greek islands to help Athens cope with the massive influx of migrants to its shores.
The guards "will assist in identifying and fingerprinting of arriving migrants, along with interpreters and forged document experts," Frontex said in a statement.
"The number of border guards deployed will gradually increase to over 400 officers as well as additional vessels, vehicles and other technical equipment," it added.
More than one million migrants and refugees have landed in Europe this year, with more than 800,000 coming via Greece.
At least 3,692 have died attempting to reach Europe across the Mediterranean, according to the International Organization for Migration (IOM).
