Here's a look at some of the stories that CNN plans to follow this week:
Romney targets Obama as Gingrich employs survival strategy
The race for the GOP presidential nomination heads to three states holding contests this week, with former Massachusetts Gov. Mitt Romney coming off a strong win Saturday in Nevada - his second straight victory and third out of five contests in the still-young 2012 primary/caucus season.
Caucuses will be held Tuesday in Colorado and Minnesota, and a nonbinding primary will take place in Missouri. After winning Nevada on Saturday, Romney looked past his three remaining GOP challengers while talking to supporters, spending most of his time hammering away at President Barack Obama. The only time he referred to his GOP opponents was when he said he was the only one who could fix the economy, "unlike other people running for president."
Newt Gingrich, the candidate running second to Romney in the delegate count, laid out a strategy Saturday that focuses less on this week's contests and more on March 6, Super Tuesday, when 10 states hold primary elections. That includes Georgia, which he represented in Congress, as well as neighboring Tennessee. Gingrich predicted he will be close to Romney in convention delegates won after the Texas primary in April.
Wyoming also has caucuses on Thursday, and Maine is caucusing all week. Maine's multiday process ends on Saturday.
Opposition group calls for strike as Syrian violence continues
After the U.N. Security Council on Saturday failed to approve a resolution seeking to halt months of violence in Syria, groups opposed to Syrian President Bashar al-Assad are planning a civil strike for Monday to put more pressure on him.
On Saturday, Russia and China used their veto power in the Security Council to defeat a draft resolution that would have demanded al-Assad stop the killing and answer calls aimed at finding a Syrian-led solution to the 11-month crisis. The United Nations says about 6,000 people have died as a result of months of clashes in that nation. Opposition groups blame the violence on the government, saying it is cracking down on those who have been calling for al-Assad to step down. The Syrian government has consistently blamed "armed terrorist groups" for the violence.
Hundreds have been killed just in recent days, according to Syrian opposition groups. Arab League Secretary-General Nabil el-Araby insisted that despite the developments in the Security Council, the Arab League and the international community will continue to seek a resolution to the crisis, according to an Arab League official who could not be named because he is not authorized to speak to the media.
The Arab League had observers in Syria last month to monitor whether al-Assad was abiding by an agreement to end the crackdown, but the league suspended the mission last week because of a recent sharp escalation in violence.
The mission would have monitored whether al-Assad was abiding by an agreement to end the crackdown, which has resulted in an estimated 6,000 deaths, according to the United Nations.
Trial in death of Virginia lacrosse player begins
The trial of a man accused of fatally beating a University of Virginia women's lacrosse team player - his ex-girlfriend - is expected to begin this week.
George Huguely, who was a member of the UVA men's lacrosse team, faces charges including first-degree murder in the May 2010 death of Yeardley Love, 22. A medical examiner ruled that blunt force trauma killed Love, and authorities allege Huguely caused it during an altercation at Love's off-campus apartment, where a roommate found her dead days before graduation.
Jury selection is expected to begin Monday; the trial is expected to last about two weeks.
Weather posing problems in Australia, Europe
Rescuers will spend at least the early part of this week helping to evacuate thousands of residents stranded by rising floodwaters in the eastern Australian state of Queensland. Heavy rains in recent weeks have swollen rivers beyond their banks, threatening a number of communities in Queensland and New South Wales.
Authorities on Sunday were using a cargo plane and helicopters to evacuate patients from a hospital in particularly hard-hit Queensland town of St. George, where officials were warning about 4,000 residents to get out of the path of what officials say will be a record-breaking flood. The Balonne River is expected to crest Monday at 15 meters (49.2 feet), swamping St. George.
In Europe, many countries are dealing with unusual amounts of snowfall and a powerful cold snap. Dozens have died in Ukraine, Romania, Serbia and Poland; Sarajevo in Bosnia canceled school for a week as the Balkan city was hit by the biggest snowfall since 1999; and an Italian valley with 50,000 residents has been paralyzed and without power after 39 inches of snow.
A Mormon feminist pioneer
