Hungary is sending new police contingents to help patrol the Macedonian-Greek and Serbian-Macedonian borders, the national police said on its website.
The national police headquarters will send a 15-strong contingent to Serbia and a 30-member unit to Macedonia.
The police officers will be tasked with investigating and preventing illegal entry into Serbia and Macedonia and arresting people smugglers.
The units will be equipped with off-road vehicles, night vision devices and thermal cameras.
Over the past three years, Hungarian police have apprehended some 7,000 illegal migrants in the two countries, the statement said.
