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.

U.S. President Donald Trump said on Friday that he estimates a deal with Iran will be signed "in the next day or two."
Trump said in an interview with Israel's Channel 12 News that the United States and Iran will probably meet over the weekend to finalize a deal to end the war. "The Iranians want to meet and make a deal," he said.
He said "the naval blockade on Iran is helping to make a deal. I will not lift it until we make a deal," adding that "the biggest part of this deal is that it will make Israel safer. This deal is good for Israel."
According to the channel, one component of the deal under discussion is that the United States will release 20 billion U.S. dollars in frozen Iranian funds.
In exchange, Iran would give up its stockpile of enriched uranium, and would be only allowed to have nuclear research reactors to produce medical isotopes, all above ground.
Trump also stressed that Israel must stop the strikes on Lebanon, saying, "They can't keep blowing up buildings. I'm not going to allow that."
Also on Friday, Trump said in a phone interview with Bloomberg that a deal to end the U.S.-Israeli war with Iran is mostly complete as talks over a lasting peace deal will "probably" be held this weekend in Pakistan.
Trump said in the phone interview that Iran agreed to suspend its nuclear program indefinitely, and will not receive any frozen funds from the United States.
"Most of the main points are finalized. It'll go pretty quickly," Trump said.
Asked if he would travel to Pakistan to sign the potential deal, Trump said: "I may."
Trump again denied that the moratorium on Iran's nuclear program would expire after 20 years. "No years, unlimited," Trump said.
The United States will get all of Iran's nuclear "dust" with no money having exchanged hands "in any way, shape, or form," Trump wrote on social media earlier on Friday. Multiple Western media outlets have interpreted Trump's reference to nuclear "dust" as meaning Iran's stockpile of enriched uranium.
Iran has yet to comment on any deal beyond the reopening of the Strait of Hormuz, nor on claims made by Trump that Tehran had offered concessions, including over the key issue of its nuclear program.
If the United States continues its naval blockade of the Strait of Hormuz, Iran will consider it a violation of the ceasefire between the two countries and will close the waterway, the semi-official Tasnim news agency reported Friday, citing an informed source close to the Supreme National Security Council.
The Iranian side has yet to respond to the media report on the enriched uranium issue.
The United States and Iran had their first round of negotiations in Pakistan's Islamabad last weekend to ease tension in the Middle East. The talks, which failed to produce an agreement, took place after a ceasefire was announced on April 8 between Iran, the United States, and Israel, following 40 days of fighting.
Iran tightened control over the Strait of Hormuz after the United States and Israel launched joint attacks on the country on Feb. 28. The United States also imposed a naval blockade on the strait following the failed negotiations in Islamabad.
Earlier on Friday, both Washington and Tehran confirmed that the strait had been completely open for all commercial vessels. However, Trump said on Truth Social that the U.S. naval blockade would "remain in full force." In response, Iran warned of closing the waterway again if the U.S. blockade continues.
