The United States military has said it will extend the tours of 3,200 troops in Afghanistan in order to counter an expected spring offensive by Taliban fighters.
Also on Thursday, Condoleezza Rice, the US secretary of state, said the US government would ask congress for an additional $10.6 billion in military and civil aid to Afghanistan.
The troops from the 3rd Brigade, 10th Mountain Division, were due to complete a one-year deployment next month, but their tour of duty had been extended by up to 120 days, the US defense department said in a statement.
Given other troop movements, the extension means the Pentagon will have about 2,500 more soldiers in Afghanistan than previously planned, for the next few months.
Training funds
Rice, meanwhile, told reporters she would ask congress for $8.6 billion in new money to train and equip the Afghan army and police and $2 billion for reconstruction projects.
"The challenges of the last several months have demonstrated that we want to, and should, redouble our efforts," Rice said as she flew to Brussels for a meeting of Nato foreign ministers on Friday that will focus on Afghanistan.
In 2006 more than 4,000 people died in fighting in Afghanistan and violence in the impoverished central Asian country is increasing.
Last year was the bloodiest in Afghanistan since US-led forces removed the Taliban from power in 2001 following the September 11 attacks on New York and Washington.
Shifting focus
The increase in forces comes as George Bush, the US president, is planning to send 21,500 extra troops to Iraq to combat growing sectarian violence.
Critics of Bush's policy in Iraq, including Hillary Clinton, a Democratic presidential hopeful, have urged Bush to focus instead on bolstering forces in Afghanistan.
At the Nato meeting on Friday Rice is expected to use the increased US deployment in Afghanistan to encourage other nations to commit further troops and funds to help combat the Taliban.
US army commanders have said they expect the Taliban to try to increase the level of violence again in spring, when fighting in Afghanistan traditionally picks up after a winter lull.
