FILE - In this April 6, 2013 file photo, a Chinese man uses a smartphone to take his own photo with an "Iron Man" poster together with a costumed figure, left, during a promotional event of the new movie "Iron Man 3" at the Imperial Ancestral Temple in Beijing's Forbidden City. From demanding changes in plot lines that denigrate the Chinese leadership, to dampening lurid depictions of sex and violence, Beijing is having increasing success in pressuring Hollywood into deleting movie content Beijing finds objectionable. It's even getting American studios to sanction alternative versions of films specially tailored for Chinese audiences, like "Iron Man 3," which debuts in theaters around the world later this week. The Chinese version features local heartthrob Fan Bingbing - absent from the version showing abroad - and lengthy clips of Chinese scenery that local audiences love.

Senators questioned which agencies knew of a trip to Russia by Tamerlan Tsarnaev and whether information was shared. At least 87 were killed and about 600 survivors rescued from the commercial building that housed several garment factories in Dhaka. The AP-NORC Center for Public Affairs Research poll says two-thirds of those 40 and older have done little to no planning for long-term care. Experts say older brothers often have a direct influence over younger ones, which could have steered the younger Tsarnaev brother toward the bombings.
