(Reuters) - Iranian-backed Houthi militants in Yemen have stepped up attacks on vessels in the Red Sea since November to show their support for Palestinian Islamist group Hamas fighting Israel in Gaza.
The attacks impact a route vital to East-West trade, especially of oil, as ships use the Red Sea to access the Suez Canal.
In response, some of the world's largest shipping companies have diverted vessels around southern Africa's Cape of Good Hope, adding time and costs to voyages.
Below are actions take by companies (in alphabetical order):

The global logistics group said on Dec. 22 it had rerouted more than 25 vessels around the Cape of Good Hope over the past week, and that number would likely grow.
"Blank sailings and rate increases are expected to continue across many trades into Q1 of 2024," it added.
CMA CGM
The French shipping group is planning a gradual increase in the number of vessels transiting the Suez Canal, it said on Dec. 26. "This decision is based on an in-depth evaluation of the security landscape and our commitment to the security and safety of our seafarers," CMA CGM said in a statement.
