Tributes have been paid to two British TV journalists who were killed by a car bomb in Iraq on Monday.
Four people died when the CBS crew came under attack
Sound recordist James Brolan, 42, and cameraman Paul Douglas, 48, died filming in Baghdad for US network CBS. A colleague was left critically ill.
Brolan's family said he was the "best dad, the best husband and the best mate to be with in a tight spot".
A colleague of Douglas said he was "one of those people you wanted around" when the situation got tough.
Meanwhile, the names of two UK soldiers from the Queen's Dragoon Guards, who died in a bombing in Basra at the weekend, are due to be released.
In a statement, Brolan's family said he had travelled extensively and was fascinated by the places he visited.
"His unassuming nature and love of a practical joke often belied his well-read, 'university of life' intellect.
"He always took great pleasure on the road beating his Harvard, Yale or Oxbridge-educated correspondents at Scrabble, and his knowledge of useless facts was unrivalled," they said.
"James had a natural way with people and was always in demand as the person to go with to the world's trouble spots; always putting the locals at ease, winning friends everywhere he went and always putting in his best effort."
CBS London correspondent Mark Phillips said Douglas was "one of those people you wanted around when things got dicey".
Ms Dozier remains in a serious condition in hospital
"He could charm his way through hostile country, he could defuse the belligerent tension at an armed roadblock," he added.
CBS correspondent Kimberly Dozier was also injured in Monday's attack.
The 39-year-old, who holds dual US-British citizenship and previously worked for BBC World Service radio, had an operation in a military hospital in Baghdad before being flown to Germany.
Brolan, from north London, and Douglas, from Wootton, Bedfordshire, died when the US 4th Infantry Division unit they were based with was targeted.
The attack, which also killed a US army officer and an Iraqi interpreter, was one of a wave of bombings in and around the Iraqi capital which left at least 41 dead, most of them Iraqi civilians.
The attack on the British soldiers on Sunday happened in Gizayza, north-west Basra, as they were on a routine patrol in support of operations to disrupt the insurgency.
Two other soldiers from the Queen's Dragoon Guards - a regiment which is based in Osnabruck, Germany and recruits largely from Wales - were injured in the incident.
Defence Secretary Des Browne expressed sympathy to the families of the journalists and soldiers, as well as those killed in Iraq who were not British.
"Every single loss of life is an absolute tragedy."
He said there was no timetable for the withdrawal of British troops, but they would remain until the Iraqi government was confident its own security forces were able to do their job without help from coalition troops.
"The greatest challenge is the insurgency and the terrorism. We must defeat that. And it will need to be defeated by the Iraqis themselves," he told BBC Radio 4's Today programme.
The total number of UK troops killed in operations in Iraq since 2003 now stands at 113. Nine UK service personnel have been killed this month.
