Dublin airport has massive security problems and Ryanair chief Michael O’Leary has slammed authorities there.

The airport, which is the largest in Ireland, waved on an estimated 45% of test weapons and explosives sent through its X-ray machines.

The damning report has led to calls for an urgent review of the airport’s anti-terror procedure. Ryanair CEO Michael O’Leary was particularly incensed, calling the security breach an 'international embarrassment' on a par with 'Somalia or Afghanistan.'

Real weapons and real explosives were repeatedly sent through the Irish airport's security to test the procedures and almost half of them got through the net, the Telegraph reported.

The Dublin Airport Authority (DAA) stated it could take up to two months to address the security breaches found in the EU audit of safety measures at the airport.

DAA said one of the outstanding issues had been resolved but another would take a longer time.

Minister for Transport and Tourism Leo Varadkar rushed to the airport after the security problems were unveiled and said they would be dealt with as soon as possible.

Passengers flying out of Dublin may face additional screening in other European airports the DAA stated.
