Iranian students scuffled with riot police near the Jordanian embassy on Thursday after some groups wanted to seize the building in the latest protest linked to Israel's attacks in Gaza.
Demonstrators protesting Israeli, West, demanded the mission's closure and pushed back police who had blocked the street leading to the embassy in Tehran, some briefly breaking through the cordon before being chased back.
A few hurled shoes at police, who fought back with batons.
The rally ended after a representative of Ayatollah Ali Khamenei, Iran's supreme leader, told the crowd of hundreds of people not to break into embassies or clash with police.
Israel's bombardments have prompted days of protests in the Islamic Republic, mainly by students who accuse Arab and Western leaders of not doing enough to stop the Israel. On Tuesday, students broke into a British diplomatic compound.
In another protest on Thursday, thousands of students marched in downtown Tehran, some wearing white funeral shrouds showing they were ready for martyrdom, Iranian media reported.
Khamenei, Iran's top authority, has urged Muslims to defend Palestinians whatever way they can and a group of Iranian clerics is signing up volunteers to fight in Gaza.
Iranian officials have condemned international silence and bias towards Israel.
President Mahmoud Ahmadinejad urged Arab leaders on Wednesday to act quickly to end Israeli air strikes that have killed more than 400 Palestinians.
An Iranian daily this week said student groups had written letters to the Jordanian ambassador and the head of the Egyptian mission "giving them 48 hours to choose between clearly condemning Israel's attack on Gaza or leaving Iran's soil".
Like Egypt, Jordan has a deal with Israel.
If demands were not met students would carry out their revolutionary duty as happened on 13th Aban, 1358, the Iranian date when students stormed the U.S. embassy in 1979, the Seda-ye Edalat newspaper said.
Two petrol bombs were thrown into the Jordanian compound on Tuesday without causing major damage. Cairo still rejects mainly opening a border crossing with Gaza.
