The Jews of Macedonia were rounded-up on 11 March 1943 and concentrated in an internment camp established at the tobacco warehouse called "Monopoly" in Skopje. 7,341 Macedonian Jews were imprisoned in appalling conditions. Eleven days later, 165 of the detainees, mostly doctors, pharmacists and foreign nationals were set free. The remainder of those interned were deported to Treblinka in three transports. The first, containing 2,338 Jews, left on 22 March 1943 and arrived at Treblinka on 29 March. The second, with 2,402 on board, left on 25 March and arrived on 31 March. The third left on 29 March and arrived on 5 April, carrying a further 2,404 to their deaths. 7,144 Macedonian Jews had been sent to Treblinka.

With the exception of twelve who died en route, all of them perished in the gas chambers, including 2,000 children below the age of sixteen. Only 200 Macedonian Jews survived the war. A similar number of Thracian Jews survived, either fighting with the partisans or hidden by their Christian neighbours. An undetermined number also escaped to the Italian zone of occupied Greece in 1941 and 1942.

I don't know if this qualifies as a reliable source, but it's an interesting read nevertheless.
