The death toll from Friday's Tel Aviv suicide bombing rose to five today after a woman wounded in the attack died in hospital.
The nightclub bombing, which wounded at least 50 others, shattered a truce declared at a groundbreaking summit in Egypt's Red Sea resort of Sharm el-Sheikh on February 8th.
Palestinian militant group Islamic Jihad claimed responsibility for the attack, but Israel has also blamed Damascus, saying leaders of Islamic Jihad in Syria ordered the attack.
Syria has denied responsibility.
