Bloc must be deposited in the ballot box. The ballot must be deposited without any changes." The alleged voter activity index was 97.6%. Most notably, the complete election results were published in Moscow 12 hours before the election closed. Soviet electoral documents found later substantiated that the results were completely fabricated. The Soviet authorities, having regained control over Riga and Latvia imposed a regime of terror, opening the headquarters of the KGB, massive deportations started. Hundreds of men were arrested, including leaders of the former Latvian government. The most notorious deportation, the June deportation took place on 13 and 14 June 1941, estimated at 15,600 men, women, and children, and including 20% of Latvia's last legal government. Similar deportations were repeated after the end of WWII. The building of the KGB located at 61 Brīvības iela, known as 'the corner house', is now a museum. Stalin's deportations also included thousands of Latvian Jews. (The mass deportation totalled 131,500 across the Baltics.) During the Nazi occupation, the Jewish community was forced into the Riga Ghetto and a Nazi concentration camp was constructed in Kaiserwald. On 25 October 1941, the Nazis relocated all Jews from Riga and the vicinity to the ghetto. Most of Latvia's Jews (about 24,000) were killed on 30 November and 8 December 1941 in the Rumbula massacre. By the end of the war, the remaining Baltic Germans were expelled to Germany. The Soviet Red Army re-entered Riga on 13 October 1944. In the following years the massive influx of labourers, administrators, military personnel, and their dependents from Russia and other Soviet republics started. Microdistricts of the large multi-storied housing blocks were built to house immigrant workers. By the end of the war, Riga's historical centre was heavily damaged from constant bombing. After the war, huge efforts were made to reconstruct and renovate most of the famous buildings that had been part of the skyline of the city before the war. Such buildings were, amongst others, St. Peter's Church which lost its wooden tower after a fire caused by the Wehrmacht (renovated in 1954). Another example is the House of the Blackheads, completely destroyed, its ruins subsequently demolished; a facsimile was constructed in 1995. In 1989, the percentage of Latvians in Riga had fallen to 36.5%. 21st century In 2004, the arrival of low-cost airlines resulted in cheaper flights from other European cities such as London and Berlin, and
