Qatar's prime minister said Israel has "killed any hope" of seeing more hostages returned from Gaza after carrying out an attack targeting Hamas leadership in his country.

Sheikh Mohammed bin Abdulrahman Al Thani intensified his criticism of Israeli Prime Minister Benjamin Netanyahu over Tuesday's unprecedented strike on Qatar , which killed at least six people.

"I was meeting one of the hostage's families the morning of the attack," Sheikh Mohammed told CNN in an interview aired late Wednesday.

"They are counting on this [ceasefire] mediation, they have no other hope for that."

Sheikh Mohammed added that he thought Netanyahu had "just killed any hope for those hostages".
