Sweden will send up to 600 criminals to serve their sentences in an Estonian prison under an agreement announced by the government on Wednesday aimed at reducing pressure on the country's overcrowded jails. From July next year, Sweden will be able to send men over 18 who are convicted of crimes ranging from murder to sexual offences to the prison in the Estonian city of Tartu. "The whole prison will be placed at Sweden's disposal," Justice Minister Gunnar Strommer told reporters.
