They were bored and broke

Young, aspirational and poor Vietnamese are risking their lives to travel to Europe, taking on large debts to join well-worn trafficking routes in the hope of a better future thousands of miles from their rural homes.

The dangers of illegal crossings into Europe were laid bare this week when 31 men and eight women were found dead in a refrigerated truck in Britain.

British police initially said the victims were Chinese, but it is now feared most were from Vietnam. Three suspects arrested in Britain over the deaths of 39 people have been released on bail, police said yesterday.

Many Vietnamese migrants come from just a handful of central provinces, where smugglers prey on disaffected youth lured by the prospect of overseas work.

Bored by village life and fed up with a lack of opportunity, the allure of overseas riches is enough to tempt many to embark on the risky trips.

Many belong to Vietnam's booming, social-media obsessed population of under 30s, often following relatives or friends to the UK, France and Germany -- Facebook posts from abroad and money sent home are often proof enough that the journey is worth it.

Greased by smuggling networks with links in remote Vietnamese towns and throughout eastern Europe, migrants can pay up to $40,000 for a ticket out of poverty, borrowing from relatives or taking huge loans.

"Smugglers are really saying that the UK is the 'El Dorado'," Paris-based migration expert Nadia Sebtaoui told AFP.

They are often promised princely salaries of up to £3,000 pounds ($3,800) a month, around three times the annual income in Vietnam's poorest provinces.

But the reality is often far different.

Some end up owing thousands of dollars to smugglers and money lenders who front cash for the treacherous journeys. Saddled by huge debts, many face the risk of exploitation along the way. The migrants on the ill-fated truck found this week might have paid thousands of dollars for a spot in the refrigerated trailer.

MIGRANTS FOUND SAFE

Twenty migrants were found in good health in two separate trucks in Belgium on Saturday, according to local prosecutors.

Eleven African men, women and children -- mainly from Eritrea -- were found in a truck in the city of Saint-Trond. Meanwhile, police also found nine men hidden in a truck in Bruges, in northeastern Belgium, en route to the port of Zeebrugge.
