Death of Houthi leader's brother will be detailed soon, the Saudi-led coalition backing legitimacy in Yemen said Friday, without direct admission of killing the man.
"List of the wanted among Houthi militia is a priority for the coalition to deal with terrorist persons responsible for firing ballistic missiles and threatening the Yemeni, Saudi and international security," coalition spokesman told Al-Arabiya TV on phone.
"The wanted are constantly watched and chased," Turki al-Maliki added.
"To publicize any details on the killing of Ibrahim could not be suitable now for information security, but some details will be announced later," according to Al-Arabiya.
On Friday, the Houthi group said brother of the rebel leader had been killed by "betrayal hands of the American-Israeli aggression," without further details on the assassination.
The Houthi-run interior ministry "will save no effort in chasing and arresting the criminal tools that committed the assassination," the ministry said in a statement seen by Debriefer.
Ibrahim was reportedly killed inside a department in Hadda district of Sana'a City, after he had been invited to mediate in a big dispute.
The Anadolu Agency quoted Yemeni "broadly informed" source as saying that brother of Houthi leader had been killed in his house in Hadda, to the south of Sana'a.
In November 2017, Saudi Arabia published a list of 40 people wanted over responsibility for planning, carrying out and supporting Houthi activities, including the group leader, Abdul Malik al-Houthi, his brothers (Ibrahim not including) and aides.
Yemen has been racked by a 4-year bloody conflict between the internationally-recognized Yemeni government's forces, backed by a Saudi-led coalition, and the Iranian-backed Houthi rebels who ousted the government in 2014.
Yemen conflict has triggered what the UN calls the world's worst humanitarian crisis, with most of the population in need for a type of humanitarian aid and immediate protection, including 14 million people risking famine and some 1.8 million children suffering malnutrition.
