CAIRO, March 6 (Reuters) - Yemen's Houthis said on Wednesday they had targeted the Greek-owned cargo ship True Confidence in the Gulf of Aden with missiles, causing a fire to break out onboard.

"The targeting operation came after the ship's crew rejected warning messages from the Yemeni naval forces," the militia's military spokesman Yahya Sarea said in a televised speech. (Reporting by Enas Alashray and Muhammad Al Gebaly)
