GENEVA (AP) _ Chileans continued to suffer serious human rights violations last year despite some improvement in Chile's human rights situation, a United Nations report says.

The report cites statistics compiled by the religious rights group Vicaria de la Solidaridad, listing 7,019 arrests and 62 cases of violent death blamed on persons ''linked to governent organizations.''

The report noted ''positive and encouraging events in the human rights situation in Chile which certainly will alleviate the burden of danger carried by the Chileans.''

But ''despite the progress cited, the situation is far from satisfactory,'' the report added.

It said a recent attack on the Santiago offices of the Intergovernmental Committee on Migration revealed an ''extreme danger from the private gangs'' operating in the country. It noted that the government has promised a full inquiry.

Costa Rican jurist Fernando Volio Jimenez wrote the report under a mandate from the U.N. Human Rights Commission, which will discuss it at its current session.

The report said there were no cases of involuntary disappearance in Chile in 1986 but that inquiries into 663 cases from previous years were continuing. Many of the people who disappeared are believed to have been kidnapped or killed.

It also said the government has promised to complete soon the examination of 3,099 cases involving people barred from returning to Chile from exile.

The report praised an agreement between the all-Swiss International Committee of the Red Cross and Chilean authorities that allows Red Cross delegates to visit detention centers regularly. The accord allows the Red Cross to interview without witnesses those detained, particularly ''those accused of offenses against state securyty.''

The visits will also cover those held in preventive custody. These would be aimed especially at discouraging torture and other illegal practices by judicial authorities, the report said.
