A Palestinian attacker fatally stabbed two people in a Tel Aviv office building, police said, raising to 16 the number of Israelis who have died, along with 79 Palestinians, in a wave of violence over the past seven weeks.

Two attacks by Palestinians, including a stabbing at an office building in Tel Aviv, have killed five people, intensifying a two month-long wave of violence.

Violent attacks against Jews worldwide dropped in 2013, but anti-Semitism is becoming more widespread in Europe amid a rise in popularity of extremist parties, according to a report released yesterday.
