A short-lived ceasefire between Israel and Palestinian militants in the Gaza Strip has broken down. Israeli warplanes resumed bombing parts of the besieged Palestinian territory Thursday, while members of the Islamic Jihad group fired a fresh salvo of rockets at southern Israel from Gaza. At least 34 Palestinians have been killed, and over 100 injured, since Israel assassinated Islamic Jihad leader Baha Abu al-Ata on Tuesday, killing him and his wife and injuring their children.
