American Marconi Wireless News - Tens of thousands march in Brussels against austerity plans

Grappling with a budget deficit so big that it violates EU rules, the coalition government led by Flemish nationalist Bart De Wever is looking to reform pensions and make other savings that have infuriated trade unions.

"I am here to defend my rights and those of my pupils. If things continue like this, what future will they have?," teacher Victoria Coya told AFP at the Brussels march, which drew an estimated 80,000 people according to police.

"I want our budgets to stop being cut," said the 27-year-old.

Brussels airport -- the country's largest -- cancelled all departures as security workers downed their tools. Charleroi Airport, a major European hub for low-cost airline Ryanair, said it could not operate any flights owing to lack of staff.

The strike was the latest in a series to hit Belgium since De Wever took office as prime minister in February.

Holding coloured balloons, blowing whistles and setting off smoke bombs, protesters started marching through the city in the morning, blocking traffic.

Some carried red prohibition signs with the number 67 on them, in a reference to a planned increase in the retirement age. "Right to a pension at 65," the signs read.

Others sported a picture of De Wever with the caption "wanted for pension theft".

- 'Hot air' -

Chantal Desmet, 59, said she joined the march as she was upset at the high cost of living -- and the prospect of losing her unemployment benefits.

"We are heading towards a future that doesn't look good," she said. "The government has to take notice."

Delays and cancellations also hit Brussels' metro, tram, and bus services. Police in the capital advised citizens to avoid some central areas and driving.

"This government promised more sustainable jobs and increased purchasing power. Hot air! And once again, everyone is paying, except the rich," trade union CSC said, as it urged people to join the protest.

The action will increase pressure on De Wever's coalition, which on Monday failed to agree on a budget, forcing the prime minister to postpone a key speech to parliament scheduled for Tuesday.

Trade unions have mounted strong opposition against planned reforms including cutting early retirement and a wage indexation freeze.

As it looks to find about 10 billion euros ($12 billion) in savings, Belgium -- long a laggard -- has also pledged to ramp up spending on defence as part of a NATO push to boost rearmament.

De Wever came to power after lengthy coalition talks following elections in June last year.
