A group of demonstrators gathered in Bulgaria's capital Sofia on Monday to protest against U.S. and Israeli strikes on Iran.
The protesters rallied with signs reading "Do not engage war in Iran" and "We do not welcome U.S. military aircraft", to show solidarity with Iran.
"No one has the right to launch an attack on a sovereign country or interfere in its decisions," said Kostadin Kostadinov, chairman of the Bulgarian Revival party, while delivering a speech at the rally.
"The U.S. military equipment should not be brought to Bulgarian territory and the territory cannot be used in any form for military operation against Iran. We demand the U.S. military planes to immediately leave Bulgarian territory. This is not our war. The Iranian people are not our enemy. Iran is not our enemy," Petar Nikolaev Petrov, deputy chairman of the Bulgarian Revival party, said in his speech.
Several U.S. military planes have been deployed at Sofia Airport in recent days, though the Bulgarian government denied that they were linked to U.S. military operations.
The U.S. and Israel on Saturday launched strikes against Iran, plunging the war-torn Middle East into a new round of violence. Iran has retaliated with a series of counterattacks against Israel and U.S. targets across the region.
