A woman who was killed when a bomb exploded at a crowded bus stop in Jerusalem on Wednesday was British, the British Embassy has said.
Her family in the UK has been informed.
Thirty people were also injured when the bomb, which was left in a bag on a pavement near the central bus station, exploded.
Jerusalem suffered a spate of bus bombings by Palestinian militants between 2000 and 2004 but attacks had stopped in recent years.
Witnesses said the force of the blast shook buildings over a wide area.
Israel's prime minister, Benjamin Netanyahu, has pledged to act "aggressively and responsibly" to the attack.
US President Barack Obama condemned the Jerusalem attack "as well as the rockets and mortars fired from Gaza in recent days".
