Secretary of State Hillary Rodham Clinton has arrived in Cairo in her diplomatic push to forge a truce between Israel and Gaza rulers of Hamas. Her visit comes hours after a bomb exploded on an Israeli bus in Tel Aviv, wounding several. Clinton is looking to piece together a deal to end Israel's weeklong offensive in the Gaza Strip. Clinton said the U.S. "strongly condemns" today's bus bombing, calling it a "terrorist attack." (AP Photo/Egyptian Presidency)
