IMO Secretary-General Kitack Lim has issued the following statement:  

“The recent reports of threats made to commercial shipping in the Red Sea are extremely alarming and unacceptable. Commercial shipping should never be a collateral victim of geopolitical conflicts. Any attack on commercial shipping is contrary to international maritime law, including laws which protect the freedom of navigation. Any action which might adversely affect shipping engaged in international trade must be avoided. 

Ships, cargoes and seafarers must be protected at all times. I invite Member States to work together to ensure unhindered and safe global navigation, everywhere, as a prerequisite for maintaining the world's supply chains, and in line with the framework of the Djibouti Code of Conduct.”
