Israeli police said the teen carried out the attack near Jaffa Gate after getting off a bus. The suspect, a 17-year-old Palestinian from east Jerusalem, was caught and arrested after a short chase. His name was not immediately released.

Jerusalem's Hadassah Medical Center said a 56-year-old man was being treated for stab wounds to his face, neck and hand. Dr. Shaden Salameh-Youssef, head of the emergency department at the hospital's Mount Scopus branch, said the man was moderately wounded but awake and in stable condition.

Israel's Magen David Adom rescue service said a 17-year-old boy was lightly injured with a stabbing wound in the stomach. He was hospitalized.

Jaffa Gate is one of the main entrances to the Old City, flanking the Armenian, Christian and Muslim quarters, and is typically crowded with tourists.

Violence linked to the Israeli-Palestinian conflict has surged since early last year.

At least 226 Palestinians have been killed so far this year.

The surge in bloodshed has also seen 32 Israelis, a Ukrainian and an Italian killed over the same period, according to an AFP tally based on official sources on both sides.

They include, on the Palestinian side, combatants as well as civilians and, on the Israeli side, three members of the Arab minority.
