What You Need to Know About Heartbleed, the New Security Bug Scaring the Internet

A soldier shot dead four colleagues and injured 16 others at the US Army's Fort Hood base in Texas before killing himself, the military says.

US media named the suspect as Ivan Lopez, 34, although his identity has not been officially confirmed.

The gunman had served in Iraq and had mental health problems, officials said.

President Barack Obama said he was "heartbroken" over the attack. A gun rampage at the same base in 2009 left 13 soldiers dead and 32 wounded.

Maj Nidal Hasan was sentenced to death for that attack.
