Brussels, October 16 (RHC)-- NATO Secretary General Jens Stoltenberg has expressed support for U.S. President Barack Obama's plan to slow down troops withdrawal from Afghanistan.

"I welcome Barack Obama's announcement on U.S. troops in Afghanistan. Demonstrates continued commitment," Stoltenberg said in a tweet on Thursday.

Obama announced Thursday that U.S. forces will remain in Afghanistan at their current levels throughout 2016. The decision marks yet another delay in Washington's plan to end the 14-year war.

Obama had originally planned to withdraw almost all U.S. troops from Afghanistan by the end of next year. He only wanted to keep a small, embassy-based military presence in Kabul.

"In the coming weeks, the alliance will take key decisions on the future scope of the rest of its support mission," Stoltenberg said. "The significant U.S. contribution will be an important factor as we consider the way ahead."
