Graphic Photos-Stranded Iranian refugees sew their lips shut in border protest

A group of Iranian refugees stuck at the border between Greece and Macedonia for the past four days have sewn their mouths shut in protest.

They did it hoping to persuade Macedonia to open the border and let them through on their way to western Europe.

They are joined by hundreds of other halted migrants, mo

st hailing from Iran, Morocco, Pakistan and Bangladesh, who have been barred entry to Europe as a result of countries tightening their borders following the Nov. 13 attacks in Paris.

One of the hunger strikers, a 34-year-old Iranian man named Hamid, told Reuters he's an electrical engineer and wants to immigrate "to any free country in the world."

"I cannot go back," he said. "I will be hanged."
