Prominent Palestinian spokeswoman Hanan Ashrawi held an election press conference late Tuesday morning at the Damascus Gate, police said.
Ashrawi refused to take down a Palestinian election banner she was carrying and police confiscated it, Jerusalem police spokesman Shmuel Ben-Ruby said.
Ashrawi's assistant was detained for questioning for trying to prevent a policeman from carrying out his work while a participant in the rally was detained for allegedly being in Jerusalem illegally.
According to the Oslo Accords, Palestinian political activity is forbidden in the capital.
