The Bulgarian Transport Ministry is reinstating the popular sea shuttles known as comets servicing the country's beach resorts and coastal cities.

The decision comes after a 20-year break, the Bulgarian TV channel bTV reports Sunday. The initial launch was scheduled for June 1, but the repair of the shuttles, which were purchased second hand from neighboring Greece, took longer than expected – three months.

The regular lines between the southern coastal towns of Sozopol and Nessebar and the city of Burgas begin Sunday. By the end of next week the shuttles will also service the northern Black Sea city of Varna and the adjacent "Golden Sands" resort.

There are 2 comets so far, but if there is interest, the Ministry plans to increase both their number and the routes serviced.
