A caravan of illegal migrants could set off from Greece for inner Europe “at any moment”, public television said. M1 on-site correspondent Attila Muci said the number of migrants at the Thessaloniki camp had grown significantly over the last few hours, with riot police also arriving at the scene. Muci said the hundreds of illegal migrants at the camp site had recently been joined by a group from another nearby camp. The migrants have reportedly said that they want their numbers to grow to a “critical mass” so that they cannot be held back from their trek towards the inner continent. They plan on making their way through Macedonia, Serbia and Bosnia, the correspondent said. Muci said he had been told by the migrants that they are ready to leave the camps behind even if it means losing their benefits, as they have waited in vain for years for their asylum procedures to progress. Many migrants, he said, have reportedly been told to expect the first stage of their asylum procedures to be cleared in 2022, 2023 or 2025.
