Spain is littered with vacant lots and half-built apartment complexes, where developers ran out of money when the construction bubble burst.

But in one Madrid barrio, neighbors are putting an abandoned tract of urban space to creative use.

Behind a chain link fence, in a dusty weed-filled lot between two soaring apartment blocks, Emilio de la Rosa is planting vegetables.

"Different types of products — garlic, beans, tomatoes, lettuce," he says. "We're teaching our children where tomatoes come from — not from the grocery store, but the ground."

It's not hard to figure out why the Rhodes family would want a house of their own. Their son Paul's passion for music makes it clear right away.

His mom, Tamika Rhodes, says in their last place, a two-bedroom apartment, Paul couldn't play the drums because it would have driven the neighbors crazy.

Now he, his two sisters, mom and dad live in a big, five-bedroom house in St. Paul, Minn. Rhodes says they all feel much more comfortable.

The killing of 16 Afghan civilians last Sunday is now one of the greatest points of tension between the United States and Afghanistan. U.S. Army Staff Sgt. Robert Bales allegedly killed the civilians in cold blood; those close to him say they were shocked by the news.

According to the Pentagon, Bales had been treated for a traumatic brain injury that he suffered in Iraq in 2010, though the extent of the damage is unclear.

There is still only sketchy information available about Staff Sgt. Robert Bales' recent experience in Afghanistan, but five years ago in Iraq, he was considered an excellent and upbeat soldier.

Bales is suspected of killing 16 unarmed Afghan civilians last Sunday. He has yet to be charged, and his civilian lawyers say they will meet with him at Fort Leavenworth, Kan., to learn the facts of the case.

Staff Sgt. Robert Bales' commanding officer once recommended him for a medal of valor after a major battle in Iraq.

Bales was named on Friday as the U.S. soldier who allegedly killed 16 Afghan civilians last Sunday. "I was shocked that it was him," Maj. Brent Clemmer told Austin Jenkins of the Public Radio Northwest News Network. "I am still in shock about it."

Here's one way to spend time under house arrest: The WikiLeaks creator will run for the Senate in Australia, his home country. The revelation appeared, typically, on WikiLeaks' Twitter feed:

Assange is under house arrest in England, fighting extradition to Sweden, where he's accused of two sex crimes.

The tension between the United States and Afghanistan has reached a boiling point.

More details are emerging about Staff Sgt. Robert Bales, the U.S. soldier accused of killing 16 unarmed Afghans this past week, and there is still anger over the accidental burning of copies of the Quran by soldiers on a military base.
