[EX Q]: (CNN) -- Samantha Stosur stopped Caroline Wozniacki from clinching the year-end women's No. 1 tennis ranking with a shock 6-4 6-3 victory at the WTA Championships in Qatar on Wednesday night.

The Australian romped to her second straight victory in the Maroon Group, following her revenge win over French Open champion Francesca Schiavone on Tuesday.

The Roland Garros runner-up's kick serve was a potent weapon against Wozniacki, with the triumph giving the 26-year-old every chance of reaching the semifinals ahead of her final group match against Russia's Elena Dementieva on Thursday.

It was her second victory over a top-ranked player this year, having beaten Serena Williams on the way to reaching the final in Paris.

The fifth seed fired 26 winners to Wozniacki's 14, and could afford to serve two double-faults in the deciding game before the Dane returned a backhand long on her first match-point.

Wozniacki, who thrashed seventh seed Dementieva on Tuesday, will next take on Italy's Schiavone on Thursday.

Kim Clijsters, who won the $4.5 million season-ending event in 2002 and 2003, earlier triumphed in her opening White Group match 6-2 6-3 against fellow former No. 1 Jelena Jankovic despite serving 10 double-faults.

The Belgian, returning to action after having a mole cut off her foot, broke Jankovic to love in the first game of the match and then again in the seventh.

The three-time U.S. Open champion was less impressive in the second set but had enough to see off the Serbian, who is struggling with illness in the oppressive heat in Doha.

[EX Q]: Beijing (CNN) -- The wife of Ai Weiwei was taken from the Chinese artist's studio by police Tuesday and was questioned for three hours, the high-profile dissident said.

Four policemen took Lu Qing from the Beijing studio to a nearby police station, he said.

She was released by police after questioning and is now a "criminal suspect," he said.

They have not told her what crimes she is accused of, he added.

"I think the authorities are trying to threaten me through her," he said, speculating that Lu's arrest was related to her plans to visit Taiwan for an exhibition of her husband's work.

She has now been told to stay in Beijing, he added.

Police did not respond to a CNN request for comment on the case.

"Nobody can consider himself safe or innocent in an environment like this," said the dissident, who was himself detained by police for 81 days earlier this year.

He was ultimately charged with tax evasion, and last week paid $1.3 million so he can contest the charges brought against his company, Fake Cultural Development Ltd.

Had he not paid the sum, his wife -- who legally represents the company -- would have been jailed, he said.

The government says the company owes 15 million yuan ($2.3 million). The money was raised from 30,000 contributors, he said.

His lawyer, Pu Zhiqiang, said last week that Ai intends to return the donations if he wins the case and is refunded the money.

His family and human rights advocates believe that the real reason for his imprisonment is his criticism of the Chinese government.

[EX Q]: (CNN)A 17-year-old male fatally shot an Iraqi man watching his first snowfall in his new American hometown, targeting him and then continuing to fire as the immigrant rushed to get inside, Dallas police said Friday.

Authorities don't believe the suspected shooter knew the victim, Ahmed Al-Jumaili, Dallas Police Maj. Jeff Cotner said reporters, nor do they believe he knew Al-Jumaili's ethnicity.

And they haven't given any indication Al-Jumaili had anything to do with what led the teen to head out armed in the first place -- a purported shooting at his girlfriend's apartment, if that in fact happened. Cotner said that, while there have nearby shootings that might be tied to gangs, "we (have been) unable to substantiate ... whether or not there was an actual shooting at the apartment."

What police do believe, based on witness testimony and other evidence, is that the teenager shot and killed Al-Jumaili, for whatever reason.

"When he saw Mr. Al-Jumaili and their family, he targeted them, he shot at them with intent," Cotner said of the suspect, who is under arrest. "And as Mr. Al-Jumaili ran back toward his apartment, he tracked him with his rifle and continued to fire."

Dallas police named the suspected shooter, though CNN is not identifying him yet since he's a minor and it's not clear if he'll be charged as an adult. The teen turns 18 in May, police said.

Until the fatal shots ended Al-Jumalli's life, March 4 had been a day of fun and joy for Al-Jumaili and his family.
