US Vice-President Dick Cheney has said Palestinian militant group Hamas, along with Iran and Syria, is trying to torpedo the Middle East peace process.
Mr Cheney made the remarks after breakfast with Israeli PM Ehud Olmert, as he ended a tour of the Middle East.
He met Palestinian leaders on Sunday, saying both sides needed to make painful concessions to achieve peace.
A Palestinian state was long overdue, he said, but militant rocket attacks against Israel jeopardised this.
"There is evidence that Hamas is supported by Iran and Syria and they are doing everything they can to torpedo the peace process," Mr Cheney said.
He earlier gave Israel strong backing on security issues.
