08:19 GMT, November 26, 2009 As DD India reports, British PM Gordon Brown has said several NATO nations will jointly offer 5,000 more troops for Afghanistan, as London and Washington push allies to take on a greater share of the war burden.

Brown wrote to NATO Secretary-General Anders Fogh Rasmussen to confirm that many of 10 other nations consulted by British officials in recent weeks have pledged to send reinforcements.

"Following these meetings and contacts, I am now optimistic that a majority of these countries will indeed make available increased numbers of troops, and more police trainers and civilian support," Brown wrote in his letter.

So far, Slovakia has offered 250 extra soldiers, Georgia has pledged between 700 and 1,000 soldiers, and South Korea has said it would send "several hundred" to protect its reconstruction teams.

The United States, Britain, Canada and the Netherlands have long grumbled that many NATO partners -- chiefly Germany and France -- have failed to take on a fair share of combat duties.

The US has pressed NATO and other allies for between 5,000 and 7,000 additional non-US troops.

Canadian and Dutch, however, troops are both scheduled to begin pulling out of Afghanistan.
