Some 50 migrants and refugees on Tuesday continued their blockade of railway tracks leading across Greece’s border with the Former Yugoslav Republic of Macedonia (FYROM), demanding passage so they could continue their journey to northern Europe.
Reports on Tuesday said that one protester doused himself in flammable liquid late on Monday but was prevented from setting himself on fire by fellow migrants.
The protest action began on Monday and has disrupted transport on the national rail network.
The government has been trying to evacuate a makeshift camp at Idomeni near the border crossing, where thousands still remained on Tuesday in the hope that FYROM would reopen the border.
The government agency responsible for managing the refugee crisis said on Tuesday that the number of migrants trapped in the country's borders has swelled to over 52,000.
