WASHINGTON (Reuters) - The United States will not end airstrikes in Afghanistan as demanded by President Hamid Karzai after two villages were hit by US warplanes last week, White House National Security Advisor James Jones said on Sunday. Civilian casualties from US airstrikes have caused friction between the Afghan government and the United States. Karzai made his demand last week during a visit to Washington in which he met President Barack Obama. Were going to take a look at trying to make sure that we correct those things we can correct, but certainly to tie the hands of our commanders and say were not going to conduct airstrikes, it would be imprudent, Jones, a retired US Marine Corps general, told the ABC programme 'This Week. Asked what reaction he expected from Karzai, Jones said: I think he understands that we have to have the full complement of our offensive military power when we need it. ... We cant fight with one hand tied behind our back. But Jones said the United States took seriously the issue of civilian casualties and would 'redouble our efforts to make sure that innocent civilians are not killed. Speaking on 'Fox News Sunday, Army General David Petraeus, who as head of US Central Command oversees military operations in Afghanistan, said he had named a US brigadier general to look at the use of airstrikes in Afghanistan. Petraeus, who said he spoke to Karzai about airstrikes, said it was important to ensure 'that our tactical actions dont undermine our strategic goals and objectives.
