Washington (CNN) - Alan Gross, the former American subcontractor who's spent four years imprisoned in Cuba, ended a hunger strike Friday that he launched last week in a bid to spur both the United States and Cuba to resolve his case.
Gross told his attorney Scott Gilbert that he would end his hunger strike, at the urging of family and friends who were concerned with his deteriorating health, but more protest would come.

"There will be no cause for further intense protest when both governments show more concern for human beings and less malice and derision toward each other," Gross told his attorney, according to a statement distributed by his U.S.-based public relations firm.
Gross called earlier this week on President Barack Obama to become personally involved in securing his release from the small Cuban jail where he's been incarcerated since 2009. Gross' lawyer on Tuesday said the U.S. government had put a resolution to his case in jeopardy after secretly setting up a social media network designed to help Cubans communicate.
"I am fasting to object to mistruths, deceptions, and inaction by both governments, not only regarding their shared responsibility for my arbitrary detention, but also because of the lack of any reasonable or valid effort to resolve this shameful ordeal," Gross wrote in a statement announcing the fast.
"Once again, I am calling on President Obama to get personally involved in ending this stand-off so that I can return home to my wife and daughters," he wrote.
Gross, who was working for the U.S. Agency for International Development when he was arrested, was charged by a Cuban court in 2011 of being an American spy. USAID has said he was in the country working on a U.S. government project setting up satellite internet connections.
Earlier this week, the U.S. government acknowledged the aid agency had secretly built a Twitter-like social media network meant to help Cubans communicate, though officials denied the website was meant to undermine the island's leftist government. The website was first made public in a report from the Associated Press.
Gross told Gilbert on Tuesday that the social media effort was "the last straw" in his determination to go on the hunger strike.
In a statement, Gilbert criticized USAID for setting up the network, called Zunzuneo. Gilbert said the disclosure had put Gross case in danger.
"Once Alan was arrested, it is shocking that USAID would imperil his safety even further by running a covert operation in Cuba," Gilbert said. "USAID has made one absurdly bad decision after another. Running this program is contrary to everything we have been told by high-level representatives of the Obama Administration about USAID's activities in Cuba."
Gross last ate solid food in the evening of April 2, though he continues to drink water, according to his lawyer, and so far on the hunger strike, he's lost 10 pounds.
"When I asked him how long he planned to continue the hunger strike," Gilbert said in a statement. "[H]e said, 'as long as it takes.'"
Since Gross was arrested, he's lost more than 110 pounds, according to his representatives. They note he's confined in his cell for 23 hours a day, where lights remain on throughout the night.
The 64-year-old still has 11 years remaining on his 15-year sentence.
"I've been begging our government for more than four years to bring Alan home," his wife, Judy Gross, said on Tuesday. "I'm worried sick about Alan's health, and I don't think he can survive much more of this."
