The blockade that has been staged by Greek farmers on the border with Bulgaria for nearly a month is "threatening to disrupt relations between the two countries", daily Kathimerini has noted. In a news report, it informs that the Parliament in Sofia approved a resolution calling on the EU to help end the blockade at Kulata-Promachonas border crossing. It also recalls the support thrown by the Bulgarian government behind the "counter-blockade" organized by road transport firms.
