UNITED NATIONS (CNN) -- In an effort to clarify its position yet again, Iraq late Saturday night said its decision to suspend cooperation with U.N. weapons inspectors was now "void."

In another letter to the U.N. Security Council, Iraq's ambassador to the U.N., Nizar Hamdoon, again tried to explain Iraq's position and to address U.S. concerns that Iraq was still attaching conditions to cooperation with UNSCOM weapons inspectors.

The letter, addressed to the current U.N. Security Council president, acting U.S. Ambassador Peter Burleigh, says, "It is evident that the Iraqi decision of 14 November 1998 means that the previous decisions concerning restricting or suspending cooperation with UNSCOM and IAEA (International Atomic Energy Agency) have become void, and that UNSCOM and IAEA can immediately resume all their activities according to the relevant resolutions of the Security Council."

This is the second letter within the space of three hours from Hamdoon to the Security Council. After Hamdoon's earlier letter clarifying Iraq's position, the United States was not satisfied and wanted a firm statement from a higher level, such as Iraq's Deputy Prime Minister Tariq Aziz or Saddam Hussein.

Early Saturday, Aziz sent a written response to a letter from U.N. Secretary-General Kofi Annan.

Iraq's letter said the country had "decided to resume working with" weapons inspectors, but attached was an addendum that conveyed points Iraq was hoping to achieve under a comprehensive review of Iraqi compliance.

Diplomats, in particular those from the United States and Britain, seized on the addendum, or annex, as evidence of further tying conditions to cooperation.

The Security Council late Saturday continued to grapple behind closed doors with how to respond to the flurry of letters.
