The Lithuanian prosecutor-general's office says Russia has asked for legal assistance over Lithuanians who defied orders to do their Soviet military service in 1990-91, the Delfi news portal reports . But the request was denied, a spokeswoman says, since it does not involve a criminal offence in Lithuania. The news has prompted Lithuanian security services to strongly advise the relevant people not to go to Russia or other non-EU and non-Nato countries for now. Doing so could "jeopardise the personal safety of citizens", they say.
