Qatar has banned some owners of construction companies, contractors and consulting engineers from leaving the country as it carries out a probe into how heavy rains damaged buildings and roadways, said a report.

The investigation already is examining the work of five unnamed companies and others could be targeted as well in the probe launched by Prime Minister Shaikh Abdullah bin Nasser Bin Khalifa Al Thani, who also serves as interior minister, the country’s state-run Qatar News Agency (QNA) said.

A year’s worth of rain on Wednesday deluged Doha’s $15-billion Hamad International Airport, the home of Qatar Airways, pouring through at least one part of the roof in the oil-rich nation which is set to host the 2022 Fifa World Cup.

The rainwater also flooded streets and shut down some stores in capital Doha, stated the report.

Announcing the ban, the QNA said "owners of companies, contractors and consulting engineers would not be permitted to travel abroad until the end of the probe."

“Parties responsible for dereliction or negligence, whether governmental or private, will be held accountable,” it added, citing a government statement.
