As an uprising in Libya approaches the start of its fourth week, the stage appears set for more bloody battles as pro-government and opposition forces grapple for key cities along the Mediterranean Sea. Here is a look at this and some of the other stories CNN plans to follow this week:
Libyan government and opposition in battle for territory, minds
Sunday - a day of heavy fighting in some areas of Libya - witnessed a bizarre clash of claims from both sides, with the opposition saying it had repelled attacks from pro-government troopsÂ in places such as the keyÂ north-central LibyanÂ city of Misrata, where 42 were said to haveÂ been killedÂ in fighting onÂ Sunday, while a pro-government rally in Tripoli celebrated what participants said were government victories in the same cities.
Opposition forces, said to be bolstered by weapon cachesÂ previously under the Libyan government's control, are seeking the ouster of Libyan leader MoammarÂ Gadhafi after his nearly 42-year rule. It'sÂ the kind of revolution that was seen in neighboring Tunisia and Egypt, but unlike in those countries, the uprising has turned into warfare. Death toll estimates range from more than 1,000 to as many as 2,000, and the international community has been pondering strategies on how to end the violence and remove the Gadhafi regime. Meanwhile, aÂ council inÂ Libya's second-largest city, opposition-held Benghazi, says it is the country's sole legitimate representative and will stay in Benghazi until Tripoli is out of Gadhafi's grasp.
Libya is one of the countries in Africa and the Middle EastÂ hit by unrest in the past couple ofÂ months. Read more details on the situations in the other nations.
U.N. sending more troops to Ivory Coast as violence escalates
The United Nations says it's planning to send 2,000 more troopsÂ to its peacekeeping mission in the Ivory Coast because of escalating violence stoked by a disputed presidential election. Last week, at least six women were fatally shot in Abidjan while protesting the refusal of the incumbent leader, Laurent Gbagbo, to step down. The United Nations says about 365 people have been killed since December in violence between supporters of GbagboÂ and his challenger, AlassaneÂ Ouattara, whom theÂ U.N. says defeated Gbagbo in November's election. World leaders are concerned that the standoff will cause a civil war like one that ravagedÂ the country in 2002.
