Striking Greek taxi drivers are blocking road access to the country's main airport and harbour in their latest protest against government reforms.
Officials at Athens International Airport advised travellers to use airport shuttle trains after hundreds of taxi drivers blocked most lanes on the main access highway.
Traffic jams also built up at the capital's port of Piraeus, where taxi drivers blocked a road leading to the cruise ship terminal.
Greece is enacting major economic reforms alongside an austerity programme as it grapples with a major debt crisis that nearly saw it go bankrupt earlier this month.
Taxi drivers started a two-day strike in protest at the government's decision to liberalise dozens of tightly-regulated professions.
