The United Nations human rights agency says the recent suicides at the U.S. detention center in Guantanamo Bay, Cuba, did not come as a surprise.

A spokesman for the U.N. High Commissioner for Human Rights, Jose Diaz, says the focus of attention should be on closing the facility - an argument that has been made by others, including international humanitarian groups and foreign governments.

The International Committee of the Red Cross plans to send a team to the detention center later this week to assess the situation.

Two Saudis and a Yemeni hanged themselves with sheets and clothes in their cells Saturday. 

Attorneys for Guantanamo detainees want the U.S. to allow independent medical exams of the remaining prisoners. 

There are more than 400 detainees being held at Guantanamo on suspicion of links to al-Qaida and the Taleban.

President Bush has said he would like to close the prison facility, but he did not say when.
