The trip of Prince William and Kate Middleton to Pakistan next week will be one of the greatest security challenges the royal family has ever faced.
Kensington Palace faces a climate of terror and security threats as the royal couple visit the troubled region.
Kate and Wills leave on Monday for a journey through Islamabad, the northern countryside and Lahore – which was hit by a suicide bombing a few months ago – when they want to cover 1,000 km of Pakistani territory.
In a statement released before the trip, the palace described it as one of the most difficult royal tours undertaken by the Cambridges.
The couple will be the first member of the royal family to visit Pakistan since Prince Charles and Camilla traveled there in 2006. Princess Diana also traveled to Pakistan in 1996.
At the request of the Foreign Office, the couple should pay an official visit to Pakistan between the 14th and 18th of October.
The palace was forced to plan a trip in the midst of increasing unrest in Pakistan, where resistance to Indian rule in Kashimr is intensifying.
Travel warnings to Pakistan warn of the threat of ransom and militants targeting the West – warning of the possibility of "indiscriminate" terrorist attacks by ISIS and local Taliban factions operating in the state.
Tensions in Pakistan have worsened in recent months after India lifted the sensitive special status of Kashmir – a hotly contested area that has been claimed by both sides in the past.
The Indian ruling party Bharatiya Janata has revoked an article guaranteeing the special status of the disputed region, effectively ending 70 years of autonomy and causing turmoil in the region.
The declaration of the palace states that the challenge is to plan the journey: "This is the most complex tour the Duke and the Duchess have undertaken so far, taking into account the logistical and security aspects.
"Pakistan is home to one of Britain's largest overseas networks, and the British High Commission in Islamabad is one of the UK's largest diplomatic missions worldwide."
Kate and William will meet young Pakistanis and learn how local communities are responding to and responding to the impacts of climate change.
Mohammad Nafees Zakaria, High Commissioner for Pakistan in the United Kingdom, said earlier this month that the trip would strengthen the historic links between England and Pakistan.
He welcomed the couple's visit and said the trip was "an expression of the importance that the United Kingdom attaches to its relations with Pakistan.
"The two countries have historical ties that further strengthen both sides."
The British Foreign Travel Advisory for Pakistan warns of the risk of "indiscriminate" terror threats against Westerners from Tehrik-e Taleba Pakistan and Daesh (ISIS, also known as the Islamic State).
Several attacks this year were directed against police and government personnel in Pakistan.
Heboll Ahrar – a splinter group from Jamaat-ul-Ahrar and Tehrik-i-Taliban Pakistan – took responsibility for the deadly suicide attack on a security vehicle on a large Sufi shrine in Lahore, killing 13 people and injuring dozens.
His council warns of the ongoing conflicts in Syria and Iraq and increases the risk of attacks on Britons abroad.
The Federal Foreign Office warns of earlier "complex and deadly" attacks by militants, including bombings, suicide bombings, grenades and shootings targeting "un-Islamic" websites such as DVD stores and barbershops.
It warns travelers about large organized gatherings and says that densely populated and unsafe markets, shopping malls, hotels, schools and live music events that could be targeted should be avoided.
The UK warned against vigilance in participating in recently reintroduced sporting events, such as cricket.
The council also recommends avoiding places of worship such as churches and urban buildings, as religious groups and government buildings are threatened by local attacks.
The council also warns of ransom motivating kidnappers.
