Greece plans to build sea barrier off Lesbos to deter migrants

Defence ministry says floating barrier will stop migrants crossing from Turkey

The Greek government has been criticised after announcing it will build a floating barrier to deter thousands of people from making often perilous sea journeys from Turkey to Aegean islands on Europe's periphery.

The centre-right administration unveiled the measure on Thursday, following its pledge to take a tougher stance on undocumented migrants accessing the country.
