State news agency TAP says both people killed were demonstrators, while the injured include protestors and police.
TAP cited the health ministry.
Thousands of demonstrators have massed outside the embassy and several were seen climbing the outer wall of the embassy grounds and raising a flag on which was written the Muslim profession of faith, an Associated Press reporter on the scene says.
Police responded by firing tear gas, and police gunfire could be heard.
