The prime minister of Yemen's Houthi government and several other ministers were killed in an Israeli strike on the capital Sanaa, the news agency run by the group said on Saturday, citing a statement by the head of the Houthi Supreme Political Council, Mahdi al-Mashat.
A number of others were wounded in Thursday's strike, it said, without providing details.
Israel said on Friday that the airstrike had targeted the Iran-aligned group's chief of staff, defense minister and other senior officials and that it was verifying the outcome.
Mashat's statement did not make clear whether the Houthi defense minister was among the casualties.
