HARI SREENIVASAN: Heavily armed police moved deeper into the snow-covered mountains east of Los Angeles today, hunting an ex-police officer wanted for three murders. Christopher Dorner's burning truck was found yesterday near the Big Bear Lake Resort, about 80 miles from Los Angeles.
Today, San Bernardino County Sheriff John McMahon said, so far, there's been no sign of Dorner himself.
SHERIFF JOHN MCMAHON, San Bernardino County, Calif.: We saw the tracks, as I indicated last night. We followed those tracks around through the forest. We haven't found any new information to suggest the tracks are going to any specific area.
We're going to continue searching until either we discover that he left the mountain or we find him, one of the two.
HARI SREENIVASAN: Dorner was fired from the L.A. Police Department in 2008. This week, he left an angry manifesto on Facebook, in effect declaring war on the police.
At least 36 people were killed in Iraq today in the worst attacks since November. Nearly 100 others were wounded. Car bombings hit two outdoor markets in Baghdad and in the Hillah Province to the south. A taxi stand in Karbala was also targeted. All three were in primarily Shiite areas. Amid the violence, thousands of Sunnis protested against Shiite Prime Minister Nouri al-Maliki.
In Tunisia, huge crowds of mourners protested as opposition leader Chokri Belaid was laid to rest. He was assassinated earlier this week. Tens of thousands converged on the cemetery, with Belaid's coffin draped in a Tunisian flag. Violence erupted as police fired tear gas and demonstrators threw stones and set cars ablaze.
Thousands of demonstrators turned out in Cairo and other cities across Egypt, protesting President Mohammed Morsi and his Islamist-led government. The crowds defied hard-line Muslim clerics, who called on their supporters to kill opposition leaders. As night fell, security forces used tear gas to disperse protesters, who threw rocks and fire bombs at the presidential palace.
Gunmen in Nigeria have killed at least nine women working to immunize children against the polio virus. The attacks today were in Kano, in the African nation's Muslim north. The killers were believed to come from Boko Haram, a radical Islamic sect. Polio remains endemic in Nigeria, but some Muslim clerics have charged the vaccinations are a plot to sterilize young girls.
The British government today condemned the growing discoveries of horsemeat in what was supposed to be imported beef. Officials said they now suspect criminals are involved.
We have a report from Chris Choi of Independent Television News.
CHRIS CHOI: Some of Britain's biggest brands are on the hook as this meat scandal grows. Now government has ordered thousands of beef products be tested, as companies recall ready meals bought by millions. And, tonight, this industry is under pressure.
PRIME MINISTER DAVID CAMERON, Britain: It is about food labeling, proper retailing, proper information. And, frankly, it's also about customers being let down.
CHRIS CHOI: This new wave of scandal started on Saturday. A Luxembourg factory supplying Findus warned them of trouble. DNA tests had started even before that.
But it wasn't until Monday that retailers were told, as Findus then withdrew its frozen beef lasagna. On Tuesday, Tesco and Aldi began to withdraw their products that came from the same supplier. And on Wednesday, tests confirmed horsemeat in Findus lasagna. But there are signs problem could go back months to August last year.
Some shops are only now removing these products, which come from Comigel, a French firm. Information it gave to Findus on Monday is revealed in a letter shown to us. It warns that raw materials delivered since the 1st of August 2012 may not match how they're labeled. In other words, the roots of this alert could go back much further than previously thought.
Crucially, do we yet know who else was supplied by that French factory?
ANDREW RHODES, Food Standards Agency: We're in communication with the French authorities to obtain a list of all the ...
CHRIS CHOI: So you still haven't got a list? You still at this stage haven't got a list?
ANDREW RHODES: Just pause a second.
CHRIS CHOI: No. Have you got a list or not?
ANDREW RHODES: I just -- just a second.
CHRIS CHOI: And after checking, he told me they still have not had a list from the French. Tonight, there are calls for a ban on all meat imports until a clearer picture emerges.
Findus and the French firm Comigel say there is no health risk and they are ensuring this can't happen again. But, tonight, as shoppers fear processed meat is not what is labeled and the ingredient increasingly missing from our food chain is trust.
HARI SREENIVASAN: Horsemeat is considered a delicacy in France and Italy, where it is openly labeled and consumed.
The U.S. Secret Service is investigating the apparent hacking of private e-mails from former Presidents George H.W. Bush and his son, George W. Bush, and other family members. The Smoking Gun website reported today that the hacker known by the alias Guccifer gained access to e-mails, as well as photos, phone numbers and addresses. Another Bush son, former Florida Gov. Jeb Bush, called the hacking outrageous.
