Iraq backs down

Iraq has acted to avert a western military strike by agreeing to allow UN weapons inspections to resume.
In the letter, Mr Aziz said the reason for the decision was "to give an additional chance to achieve justice by lifting the embargo".
Forces still on alert - Blair
"Any conditions of this nature are unacceptable. Compliance with the agreement must be absolute."
The prime minister said there could be "no negotiation, no further deals, no more amendments".
Clinton cancels trip
Mr Blair was speaking after a series of telephone conversations with President Clinton, who has now cancelled a foreign visit to concentrate on developments concerning Iraq.
A White House spokesman said Vice-President Al Gore would represent Mr Clinton at the Asia Pacific Forum meeting taking place in Malaysia.
The president still hopes to complete the latter stages of his planned Asian tour by visiting Japan, South Korea and Guam.
Annan: 'Requirements met'
Earlier Mr Annan said in New York that in his opinion the Iraqi response met UN requirements.
He is due to present the letter to the UN Security Council, which is meeting to discuss the weapons crisis later in the day.
A naval battle group fronted by the aircraft carrier Enterprise has been ordered to speed up its arrival in the Gulf and 129 more fighter planes - including 18 B-1 and B-52 bombers and 12 F-117A radar-evading stealth planes - have been sent to the region.
President Clinton's national security advisers are meeting to assess the Iraqi move.
According to Washington Correspondent Stephen Sackur, Baghdad's announcement is being treated with scepticism.
France and Russia have responded more favourably to the news.
French President Jacques Chirac, visiting Mexico City, said the "pledges must now be put into practice".
Iraq's UN ambassador Nizar Hamdoon said the inspectors would be allowed to return immediately.
"They will be allowed any minute they want to to go back and to resume their normal work," he said.
"From now on it's up to them to decide when to go back."
A UN spokeswoman in Bahrain said the inspectors were awaiting word from New York on the latest developments.
She said the earliest they could return to Iraq was Sunday.
There are nearly 100 inspectors based in Bahrain, some of whom have returned to their home countries after they pulled out of Iraq.
