The United Nations World Food program has condemned the hijacking of another ship it hired to transport food to Somalians suffering from famine.

The WFP says the ship Miltzow was being unloaded Wednesday afternoon at the port of Merka when a group of gunmen boarded and forced the crew to sail out of the port.

The Miltzow was carrying maize, beans and cooking oil.

On Monday, the freighter Torgelow was hijacked off the eastern coast of Somalia. The Torgelow was carrying fuel and supplies to another ship, the Semlow, which was recently freed by hijackers.

The Semlow was hijacked in June as it sailed from Kenya to Somalia with a load of rice donated by Japan and Germany.
