ISLAMABAD – Ahmad Waqas Goraya couldn't see anything through the black hood, but he could hear the screams.

A Pakistani blogger with a penchant for criticizing Pakistan's powerful military and taking the government to task, Goraya was kidnapped in January along with four other bloggers.

"I could hear the screams of torture," he said, struggling for words as the memories flooded back. "I don't even want to think about what they did."
