April 30 (Reuters) - Carnival's Princess banner

is revising itineraries of two of its cruises undertaking a

global voyage next year, amid uncertainties in the Red Sea, the

cruise operator said on Tuesday.

The company said the banner's two "2025 World Cruises" -

Island Princess and Crown Princess - would no longer be visiting

the Middle East and Asia, and instead would offer new port stops

in Africa and Europe.

Cruise operators such as Carnival and rival Royal Caribbean

are exercising caution as attacks by Iranian-backed

Houthi militants on vessels in the Red Sea disrupt shipping in

the Suez Canal, the fastest sea route between Asia and Europe.

Carnival had said in March it will probably not be sailing

through the Red Sea region for the rest of this year and early

next year due to persisting hostilities.

The cruise operator said on Tuesday that Island Princess -

which was scheduled to depart from the U.S. in January - would

now depart from Sydney in Australia in February and travel via

South Africa to end its journey at Malta.

Crown Princess - which is scheduled to visit 42 destinations

in 22 countries - will also travel via Africa. However, the

company did not provide more details on the full revised

itinerary for the ship.
