Israel has accused Syria of involvement in Friday night’s suicide bombing that seriously dented peace hopes in the Middle East. The attack outside a nightclub in Tel Aviv killed four Israelis and left dozens of others injured. Islamic Jihad, a Palestinian militant group with ties to Damascus, said it was responsible. Syria denies any link to the blast. With the suspected bomber identified as coming from a village in the West Bank, Israeli and Palestinian authorities have made several arrests. Israel also announced it was suspending plans for a phased pullback from a number of towns and cities until Palestinian security forces rein in militant factions.Palestinian President Mahmoud Abbas condemned the attack, blaming what he would only describe as a “third party.” “We will not hesitate for a minute in capturing the people responsible and bringing them to justice to be punished,” he said. As for Israel’s response, officials say it will show restraint for now. The first suicide bombing in Israel for four months sent shockwaves through the population. Many people believed the groundbreaking Sharm al-Sheikh summit meant such horrors were now behind them.
