Eyewitnesses say they saw a person plant an explosive and run away. Al-Arabiya reported that at least one of the suspected terrorists was a woman.
"A bomb exploded on a bus in central Tel Aviv. This was a terrorist attack. Most of the injured suffered only mild injuries," said Ofir Gendelman, a spokesman for Prime Minister Benjamin Netanyahu.
Celebratory gunfire rang out in Gaza City when local radio stations reported news of the Tel Aviv explosion. Hamas spokesman Sami Abu Zuhri praised the bombing, "Hamas blesses the attack in Tel Aviv and sees it as a natural response to the Israeli massacres...in Gaza."
