Police spokesman Micky Rosenfeld told the Associated Press that at least three were "moderately to seriously hurt" in Wednesday morning's explosion. Early reports indicated about 10 had been injured; CNN later reported the number was up to 22. There were no casualties.
In a statement, the White House condemned the bus attack:
Our thoughts and prayers are with the families of those injured, and with the people of Israel. These attacks against innocent Israeli civilians are outrageous. The United States will stand with our Israeli allies, and provide whatever assistance is necessary to identify and bring to justice the perpetrators of this attack. The United States reaffirms our unshakeable commitment to Israel’s security and our deep friendship and solidarity with the Israeli people.
Over the past week, Israel has lost five people to rockets fired from Palestinian militants. Gaza has lost 130. The last bomb attack in Tel Aviv was in 2006, the AP notes, when a suicide bomber killed 11 at a sandwich stand.
