Arab League sending mixed signals about air strikes in Libya
After an international military coalition began implementing a no-fly zone over Libya and pounding Libyan air defenses over the weekend, U.S. President Barack Obama and his national security team has been trying to shore up support for the operation among Arab governments. The Arab League, which earlier this month asked the United Nations to authorize a no-fly zone to protect Libyan civilians during the country's civil war, has been sending mixed signals about its current stance, with Secretary-General Amre Moussa reportedly saying Sunday that the operation is different from what was intended. U.S. officials, including Obama himself, are calling Arab governments, insisting that the coalition's actions - including air strikes on air-defense targets to ensure pilots can enforce the no-fly zone safely - are necessary and fall under the authorization of a U.N. resolution that passed last week.
Libyan rebels had called on international action to help them stave off assaults by Libyan government forces on their positions in Benghazi and other enclaves. The coalition's intervention, which started Saturday, comes two days after the U.N. Security Council passed a resolution authorizing the use of force, including a no-fly zone, to "protect civilians and civilian populated areas" from government attack.
"A true hero, Mohammed Nabbous of Sawt Libia al-Hurra, the Voice of Free Libya, was killed in fighting in Benghazi today."
It was a stark, raw tweet from Ben Wedeman with a big impact on our newsroom Saturday morning.
One of our first and most-trusted sources of information on the conflict in Libya had become a victim of the very civil war he in some ways had helped to spark.
In the first few days of the conflict back in February, "Mo" as we called him had become an inspiration, friend and "go-to" source as well as a regular witness on CNN's shows.
Of course, you wouldn't know that from watching.
We blurred his face and gave him code-names like "Benghazi Protester" in order to protect him and his young family.
It was a struggle to keep him from blurting out his name and even phone number on air, sometimes, as Mohammed said that he wanted freedom for Libya, or to be martyred trying to achieve it.
AT&T will acquire T-Mobile USA from Deutsche Telekom for an estimated $39 billion, the companies said in a joint release Sunday.
Egyptian voters overwhelmingly approved proposed constitutional amendments that pave the way for parliamentary elections in June, according to the head of the judicial committee overseeing the referendum.
"We are proud of the Egyptian people for deciding their own destiny," Judge Mahmoud Atiya said Sunday. "We assure the world that the March 19 referendum was fair and transparent at all stages."
Of the 18,366,764 ballots cast Saturday, there were 14,192,577 "yes" votes and 4,174,187 "no" votes, Atiya said.FULL STORY

[10:51 p.m. Sunday ET, 4:51 a.m. Monday in Libya] An announced list of the countries participating in the military coalition: The United States, Belgium, Britain, Canada, Denmark, France, Italy, Norway, Qatar and Spain.
U.S. officials have said they plan to hand over operational control of the military mission in coming days.
[8:55 p.m. Sunday ET, 2:55 a.m. Monday in Libya] In the following video, CNN's Nic Robertson reports on his visit to the building - in Libyan leader Moammar Gadhafi's compound in Tripoli - that apparently was struck in a coalition airstrike Sunday night. (A coalition official confirmed, after Robertson's report, that it had targeted the compound.)
[8:36 p.m. Sunday ET, 2:36 a.m. Monday in Libya] A coalition military official has confirmed that Libyan leader Moammar Gadhafi's compound in Tripoli was targeted by airstrikes Sunday night, CNN's Chris Lawrence reported.
The official said the compound was targeted because it contains capabilities to exercise command and control over Libyan forces and the coalition goal is to degrade his military capabilities. The official said neither Gadhafi nor his residence was the intended target.
Earlier, the Libyan government said at least one missile struck a building inside the compound Sunday night. Western journalists, including CNN's Nic Robertson, were brought inside the compound to survey the destruction.
[8:26 p.m. Sunday ET, 2:26 a.m. Monday in Libya] Oil prices jumped more than $2 a barrel in electronic trading Sunday following escalating violence in Libya, where international forces fired on Libyan defense sites, CNNMoney reported.
The benchmark U.S. contract, West Texas Intermediate, for April delivery gained $1.95 to $103.02 a barrel. The more active May contract jumped $2.08 to $103.93 a barrel.
[8:10 p.m. Sunday ET, 2:10 a.m. Monday in Libya] The Gadhafi-compound building in Tripoli that was damaged in what may have been a missile attack Sunday night is about 150 yards away from a Gadhafi building that was struck in a 1986 U.S. airstrike, CNN's Nic Robertson reported.
[7:56 p.m. Sunday ET, 1:56 a.m. Monday in Libya] A member of the Libyan opposition told CNN that the Gadhafi government collected bodies of people killed in fighting in the past week and displayed them over the weekend, trying to show they were killed by coalition airstrikes. The claim by Ahmed Gebreel, who cited eyewitnesses and medical officials, could not be verified by CNN.
The Libyan government has claimed that women, children and clerics have died in allied attacks.
[7:15 p.m. Sunday ET, 1:15 a.m. Monday in Libya] A building at Libyan leader Moammar Gadhafi's compound in Tripoli was damaged by at least one missile about 2.5 hours ago, a Libyan government official tells CNN's Nic Robertson.
Robertson said government officials took him to the four-story building. The roof has collapsed, he said. Robertson said he isn't able to verify what caused the damage, but the government's timeline coincides with a blast that Robertson heard late Sunday, and the building looks as if it were hit by missiles, Robertson reported.
Robertson said he doesn't know where Gadhafi is, and that there is no evidence that he is at the compound. No one was injured in the strike on the building, a Libyan government official told Robertson.
U.S. officials earlier Sunday said they are not targeting Gadhafi.

[4:35 p.m. Sunday ET, 5:35 a.m. Monday Tokyo] A U.S. radiation expert has said there's not much reason to worry despite restrictions on some food produced in two provinces around the Fukushima Daiichi nuclear power plant. Japan slapped on the restrictions after high levels of radioactivity turned up in spinach and milk.
Dr. James Cox, professor of radiation oncology at the M.D. Anderson Cancer Center in Houston, said the reported levels posed little or no health concerns.
