Headlines: 41 Killed in Yemen Clashes, Space Shuttle Endeavour Lands

By News Desk

At least 41 people were killed early Wednesday in Yemen’s capital Sanaa in the latest round of clashes between the government forces of President Ali Abdullah Saleh and tribal fighters.

According to the Associated Press, street fighting broke out overnight:

Fighting raged until 5 a.m., and witnesses said Presidential Guard units shelled the headquarters of an army brigade responsible for guarding sensitive government institutions. Army officers who have defected to the opposition say the government suspected the brigade commander was about to join forces with the movement to oust Saleh.

In recent days, supporters of Sheik Sadeq al-Ahmar, a powerful tribal leader who has sided with protesters against Saleh, have clashed with army units. In retaliation, President Saleh has blocked electricity and water supplies in the neighborhood where al-Ahmar resides.

On Tuesday’s NewsHour, Margaret Warner spoke to Barbara Bodine, former U.S. ambassador to Yemen, and Benard Haykel of Princeton University, about the breakdown of the cease-fire and what’s next for Saleh.

Space Shuttle Endeavour Completes Final Mission

Space Shuttle Endeavour made its final landing at the Kennedy Space Center in Florida after a two-week mission to the International Space Station. NASA plans to phase out its space shuttle program this summer, sending Atlantis on its final mission in July.

"It’s sad to see her land for the last time, but she really has a great legacy," said Commander Mark Kelly, whose wife, Arizona Rep. Gabrielle Giffords, is still recovering from being shot in January but was allowed by doctors to travel to Florida to attend the launch.

Pakistani Journalist Laid to Rest

Saleem Shahzad, whose body was found Tuesday after he went missing over the weekend, was laid to rest amid suspicion over the cause of death. Shahzad, who wrote for Asia Times Online and Adnkronos, an Italian news agency, had recently reported on connections between Pakistan’s navy and elements of al-Qaida (read his article here).

Before his death, Shahzad told of being threatened by members of Pakistan’s Inter-Services Intelligence agency, though they have denied any involvement in his death. Shahzad disappeared while driving to a television interview in Islamabad and his body was found beaten and showing signs of torture. The Pakistani government has promised an investigation into his death.

Secretary of State Hillary Clinton said, “His work reporting on terrorism and intelligence issues in Pakistan brought to light the troubles extremism poses to Pakistan’s stability.”

Pentagon to Classify Cyber Attacks as Punishable by Military Force

The Pentagon will soon issue a new policy saying that cyber attacks launched by foreign entities can be considered an act of war and responded to accordingly. Although the parameters for what would be considered a severe enough attack remain unclear, cyber attacks that target power grids or other critical infrastructure would likely be the focus of such a policy.

Because of the difficulty in pinpointing the source of a cyber attack, identifying whether a government or a non-government actor is the culprit would also complicate the policy.
