Meanwhile, Italian Defence Minister Roberta Pinotti also flew to check on the condition of Massimiliano Latorre and to show support for his family members, who are with him in India, a report in Italian news agency ANSA said.
Latorre has been responding well to treatment in the neurology department after he lost consciousness due to a mild cerebral ischemia, or restriction of blood supply, the doctors were quoted as saying by ANSA.
"I feel close to Massimiliano Latorre and I wish with all my heart that he can get back as soon as possible," Mogherini said in a statement.
Latorre and Salvatore Girone are charged with murder of two Indian fishermen during an anti-piracy mission while guarding the privately owned Italian-flagged oil-tanker MT Enrica Lexie off the coast of Kerala on February 15, 2012. They are living at the Italian embassy here after being detained two-and-a-half-years ago.
