Somalia - The UN Security Council is to vote to increase the African Union peacekeeping force in Somalia by more than 5,000 soldiers, diplomats have said.
The resolution will increase the number of troops in the country to 17,731 from its current level of 12,000.
The vote on Wednesday comes ahead of an international conference on Somalia to be held in London.
British Prime Minister David Cameron told the BBC the threat from Somalia's al-Shabab militants was "substantial".
"It is based on the fact that al-Shabab is an organisation that has now explicitly linked itself to al-Qaeda, and it encourages violent jihad not just in Somalia but also outside Somalia," Mr Cameron said.
The armed Islamist group controls many southern and central parts of Somalia, which has been without an effective central government since 1991.
Nearly 1.5 million Somalis have been forced from their homes during the conflict.
David Cameron: "The security threat is real; it is substantial."
Last year, al-Shabab was forced out of many parts of the capital, Mogadishu, by the African Union forces, along with troops loyal to the UN-backed government. Since then, the group has also lost ground in other areas.
In October, Kenyan troops crossed over the border in pursuit of al-Shabab members it blames for a series of kidnappings in Kenyan territory.
Earlier this month, they captured the key town of Badhadhe, some 180km (110 miles) south of the port of Kismayo.
Ethiopian troops have also entered Somali territory to move against the Islamist militants.
The BBC's Barbara Plett, at the UN headquarters in New York, says the idea behind the expanded African force is to degrade al-Shabab as a military force and create a space for a political solution to the country's two-decade conflict.
The council resolution sets the African troops the task of moving into new areas of Somalia "to take all necessary measures" with Somali security forces "to reduce the threat posed by al-Shabab and other armed opposition groups", according to a copy of the text seen by AFP news agency.
The African Union mission already in the country is made up of troops from Burundi, Uganda and Djibouti but will take in Kenyan soldiers now fighting in Somalia.
he resolution will also require all UN members to stop trade in charcoal from Somalia, which is causing deforestation and serious environmental damage in the drought-prone country.
