His children Jessica, six, Kyle, five, and Kayla, three, said: "For our brave Dad who went away to build sand castles and stop the bad men hurting people. We love you to the moon and back.

Last night, Lt Col Simon Bell, Commanding Officer Explosive Ordnance Disposal and Search Task Force, said: "Cpl Roberts had leadership qualities in spades.

Pte Silibaravi, originally from Fuji, had also served previously in Afghanistan and Iraq and played rugby for his regiment. Major Ben Hawkins, Officer Commanding Operations Squadron, from the task force, said: "Well respected by his team and exceptionally level-headed 'Sili" was truly a delight to be around.

Nahr-e Saraj remains one of the most dangerous and contested areas of Helmand. Since December last year, five British soldiers have been killed in bomb and gun attacks while serving in the area. The latest deaths come as members of western leaders prepare for the Nato Chicago conference later this month, which will address the future requirements of Afghanistan following the withdrawal of foreign troops at the end of 2014. The conference, which will be hosted by President Barack Obama and attended by David Cameron, will hope to secure agreement on how much funding the international community will commit to the war-torn country during what is being labelled as Afghanistan's "decade of transformation." The Afghan National Army and Police and other parts of the country's security apparatus will require funding of at least £2 billion a year for the 10 years. Other areas such as governance, education, the criminal justice system and counter-narcotics will require billions of pounds more. Britain has already agreed to fund the Afghan Army's officer training academy in Kabul, dubbed "Sandhurst in the sand," for at least four years while the SAS will also probably help train the country's special forces for several more years. Nato will also seek to establish what help, if any, non-members such as Russia, China and India are prepared to commit.
