A bomb exploded on a bus in central Tel Aviv on Wednesday, November 21, wounding 15 people in what Israeli officials said was a terrorist attack that could complicate efforts to secure a ceasefire in the Gaza Strip, Reuters reported. Celebratory gunfire rang out across Gaza as the news spread and the territory’s Islamist rulers Hamas praised the bombing, but no one claimed immediate responsibility. The blast shattered windows on the bus as it drove along a tree-lined street next to Israel’s huge defense ministry headquarters. Police said it was not a suicide attack and suggested that someone might have left the device on the number 142 bus. The last time a bomb blast hit Israel’s commercial capital was in April 2006, when a Palestinian suicide bomber killed 11 people near the old central bus station.
