Qatar's prime minister on Tuesday said Israel's military offensive in Gaza had undermined peace efforts after the release of U.S.-Israeli hostage Edan Alexander and amid expanded operations in the Palestinian territory.

"When Israeli American soldier Aidan Alexander was released, we thought that moment would open a door to end this tragedy, but the response was a more violent wave of strikes," said Sheikh Mohammed bin Abdulrahman bin Jassim Al-Thani.
