Housing and Construction Minister Uri Ariel asked US President Barack Obama to free Israeli agent Jonathan Pollard as he shook the visiting US president's hand upon his arrival at Ben-Gurion Airport on Wednesday."Please free Pollard," Ariel stated, noting that Obama listened, but did not respond.Obama said in a Channel 2 television interview last week that he had no plans to free Pollard in the immediate future."After 28 years that Pollard is caged in American captivity, I felt a personal obligation to turn directly to President Obama and to ask him to pardon Jonathan out of humanitarian considerations," Ariel stated after having met Obama.
