(JERUSALEM) — In an unprecedented measure, Israeli police barred Palestinians from Jerusalem’s Old City on Sunday in response to stabbing attacks that killed two Israelis and wounded three others, as Israel’s prime minister vowed a “harsh offensive” to counter rising violence. Tensions have flared in recent weeks over an Old City holy site sacred to Muslims and Jews, a series of so-called “lone wolf” attacks on Israelis and a security clampdown, which on Sunday saw Israeli troops launch a bloody arrest raid in the West Bank. The latest spike in violence comes at a time when many Palestinians no longer believe statehood through negotiations with Israel is possible.
