s deputy operating chief and chairman and CEO, international, made the comments while speaking on a panel with WPP PLC (WPP) CEO Sir Martin Sorrell and DreamWorks Animation SKG. Inc. (DWA) boss Jeffrey Katzenberg. "When the creative process shifts toward safety in an environment of real pressure ... it takes a while to get out of that," Murdoch said. He added that it is crucial to continue taking risks when times are tough, saying, "We must guard against fear." Murdoch acknowledged that "the mood has shifted" over the past few weeks as people in the industry worry about the macroeconomic environment because of situations like that in Greece. Still, he said his outlook hadn't changed. "We feel pretty healthy about the business," Murdoch said. "Nervous about the environment." Murdoch said News Corp. must find its place over the next decade in a shifting competitive landscape. He cited the roles of "monolithic" technoe bombing in the mountainous Azra district of Logar province, some 25 miles east of Kabul, reflect the chaos that frequently follows such an attack. The Afghan Health Ministry initially said in a statement that some 60 people were killed and 120 wounded. But at a later news conference, ministry official Abdullah Fahim told reporters those figures were wrong, and said new information put the toll at between 13 and 25 killed and 50 wounded. Din Mohammad Darwesh, a spokesman for the provincial governor, said 25 people were killed and more than 40 wounded in the blast. The different tolls could not be immediately reconciled. The bomber drove up to the medical clinic in an SUV, and clinic guards tried to prevent him from entering the center's compound, said Mohammad Zaref Nayebkhail, the provincial health director. "The driver didn't stop and he entered the compound and reached the main building of the health center, where the truck detonated," Nayebkhail said. The force of the blast caused the building housing the 10-bed clinic to collapse, trapping at least 15 people underneath the rubble. People were frantically scouring the rubble in search of bodies and survivors, he said. Nayebkhail said the clinic had recently been expanded to meet the health needs of the far-flung district's population. An emergency response team of nurses, doctors and other provincial officials was to fly by helicopter to the area to help search for survivors in the rubble of the remote clinic, he said. The Taliban denied responsibility for the bom
