Iran on Wednesday showed the first pictures of 15 detained British navy personnel after Britain froze contacts between the two in an escalating dispute over the captives.
Britain angrily condemned the images of the eight sailors and seven marines shown by Iranian television, in which the only woman among them apparently admitted that the group had trespassed into Iranian waters.
Iran said Faye Turney, 26, would soon be released but there was no easing of tensions between London and Tehran over the crisis now almost one week old.
The footage included pictures of Turney in a black headscarf, but also a letter she had written to her family.
The Britons were pictured having a meal, and Turney, the mother of a three-year-old girl, said: “Obviously we trespassed in the waters.”
Iran has insisted the Britons were in Iranian waters when detained last Friday.
“They were friendly, very hospitable, very thoughtful. Nice people,” she said of her captors.
In a letter to her family released by the Iranian embassy in London, Turney also said “I have written a letter to the Iranian people to apologise for us entering into their waters.”
She ended: “Please don't worry about me. I'm staying strong. Hopefully it won't be long until I'm home to get ready for Molly's birthday party” — a reference to her three-year-old daughter.
The report did not say when or where the footage was filmed and the authenticity of the letter could not immediately be confirmed.
An Iranian foreign ministry spokesman told AFP that Turney would be freed “within a day or two.”
But Britain reacted angrily to the images. “It is completely unacceptable for these pictures to be shown on television,” a Foreign Office spokesman told AFP in London.
“There is no doubt that all personnel were seized in Iraqi waters and were entitled to be there.”
Amid mounting tensions, heightened by US navy exercises in the Gulf, Foreign Secretary Margaret Beckett announced the freeze in government-to-government contact in a statement to the British parliament.
“We need to focus all our bilateral efforts during this phase on the resolution of this issue,” she said. “We will therefore be imposing a freeze on all other official bilateral business with Iran.”
Britain also revealed evidence that it said showed the 15 were in Iraqi waters when detained.
Iran rejected this and played down Britain's decision to freeze contacts with Tehran, saying ties were already “cold and inactive,” the official news agency IRNA quoted a foreign ministry source as saying.
British Prime Minister Tony Blair emphasised his country's determination in the dispute.
“It is now time to ratchet up the diplomatic and international pressure” on Tehran, Blair told lawmakers, adding that “there was no justification whatever” for the detention of the sailors.
“It was completely unacceptable, wrong and illegal,” he said.
The prime minister said Britain was in contact with “all our key allies” over the dispute in order to “step up the pressure” on the Iranian government.
The White House said Wednesday that US President George W. Bush fully backed Blair over the crisis.
Bush held a secured video teleconference with Blair on Wednesday at which he said he “fully backs” the British leader in the affair, White House spokeswoman Dana Perino said.
The two men spoke “on a variety of topics including this one. The president fully backs Tony Blair and our allies in Britain,” Perino said, adding the videoconference had been programmed before the 15 sailors and marines were seized.
Speaking for the European Union, German Chancellor Angela Merkel called Iran's action “unacceptable” and renewed a call for the soldiers' release.
“The British have our full solidarity here,” she said.
NATO Secretary General Jaap de Hoop Scheffer also called for their immediate release.
The captives have been held at a secret location but Turkish Prime Minister Recep Tayyip Erdogan said at an Arab summit in Saudi Arabia that diplomats from his country might be allowed access to them.
British military chiefs used maps and GPS coordinates to affirm that the navy personnel were 1.7 nautical miles (3.15 kilometres) within Iraqi waters at the northern end of the Gulf. It gave the coordinates as 29 degrees 50.36 minutes north and 48 degrees 43.08 minutes east.
The Iranian embassy in London insisted that the British personnel had “illegally entered” up to 500 metres (550 yards) within Iranian territorial waters.
But the embassy said it was “confident the two governments are capable of resolving this security case through their close contacts and cooperation.”
London argues that the captured personnel were conducting “routine” anti-smuggling operations when they were seized at gunpoint.
There has been speculation that Tehran could use the British personnel either to trade for five Iranians being held by US forces in Iraq or for concessions over Iran's controversial nuclear programme.
Beckett said Wednesday that Iran had denied any such motivation.
The United States, which has already voiced “concern and outrage” over the incident, denied that an unusual exercise involving two US aircraft carrier strike groups in the Gulf was aimed at raising tensions with Iran.
Washington said it was to reassure friends and allies.
In New York meanwhile, oil prices surged to six-month highs as Britain froze ties with Iran and rumours grew of a possible military clash between the West and the Islamic Republic.
New York's main oil futures contract, light sweet crude for delivery in May, jumped 1.15 dollars to close at 64.08 dollars a barrel.
