(Reuters) -Iranian-backed Houthi militants in Yemen have stepped up attacks on vessels in the Red Sea 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 access the Suez Canal via the Red Sea.
In response, some shipping companies have instructed vessels to instead sail around southern Africa, a slower and therefore more expensive route.
Below are actions taken by companies (in alphabetical order):
C.H. ROBINSON
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 firm said on Jan. 5 it had not changed its plans announced last month to gradually raise the number of vessels transiting through the Suez Canal.
It had previously rerouted several vessels via the Cape of Good Hope.
EURONAV
The Belgian oil tanker firm said on Dec. 18 it would avoid the Red Sea until further notice.

The German container shipping line on Jan. 9 said it would continue to divert its vessels away from the Suez Canal and around the Cape of Good Hope. It will take next decisions on Jan. 15.
It had incurred costs in a two-digit million euro range between Dec. 18-31 as a result of diverting 25 ships.
A projectile believed to be a drone struck one of its vessels sailing close to the coast of Yemen on Dec. 15. No crew were injured.
