GAZA CITY -- A bomb attack on a Tel Aviv public bus Wednesday injured at least 21 people -- three seriously -- shattering the sense of security in Israel's second-largest city and raising questions about the fate of cease-fire talks underway to end the violence in the Gaza Strip.
The noon-time attack took place on a bus on a busy downtown street. Early reports from witnesses said a man was seen running toward the bus, throwing a bag inside and running away.
Israel police launched a massive manhunt and raised security levels nationwide, fearing additional attacks might take place.
It was unclear whether the attack was related to the ongoing clashes between Israel and the Gaza-based Islamist group Hamas, but police suspected that it was a terrorist attack.
In Gaza, Palestinians cheered and celebrated on hearing the news, announced from mosque loudspeakers along with Koranic songs about victory.
"Israel has refused the truce and they want to escalate the violence, so we will have to escalate as well," said bank employee Hesham Akram, 27, in central Gaza City. "This way, Israelis will feel more insecure so they will give in to our demands for freedom."
