(ANSA-AFP) - ATHENS, 22 MAG - Greece has extended until June 7 a coronavirus lockdown imposed on the overcrowded migrant camps since March, the government announced Friday. "Measures against the propagation of the COVID-19 virus are extended for residents of the reception and identification centres across the country," the migration ministry said in a statement. The ministry did not say why the lockdown was being extended. On March 17, the government imposed the lockdown on the migrant camps both on the islands and the mainland. That was a week after a more general lockdown in the country, which was eased early this month after the apparent success in keeping the outbreak in check. On May 10, it extended the measure for the camps until May 21, and then until June 7 on Friday. As in the rest of the country, the coronavirus outbreak has had little impact on the camps. Among the 168 dead in Greece, there are no known deaths so far due to COVID-19 among the migrants, according to authorities. (ANSA-AFP).
