ISLAMABAD – A U.S. Senate delegation paid a rare visit Sunday to a tribal region along the Afghanistan border that has long been considered a stronghold of al-Qaida, the Taliban and other insurgents. The delegation led by Sen. John McCain, R-Ariz. McCain posted pictures on his Twitter account of the delegation visiting Pakistani helicopter pilots at an air base in Miram Shah. Foreigners are largely banned from the tribal region, where Pakistan has been waging a military offensive to root out insurgents for two years. The U.S. frequently carries out drone strikes in the region targeting Taliban and al-Qaida leaders.

JUDY WOODRUFF: Today, the Obama administration revealed new information that sheds light on the reality of modern warfare, the number of civilians accidentally killed in U.S. airstrikes. JOHN YANG: Today's release is the first time the White House has said how many terrorists and innocent civilians it believes have been killed by airstrikes, including by drones. Between 2009 and 2015, the administration says it launched 473 airstrikes in Pakistan, Yemen and Africa. It estimates that as many as 2,581 combatants, and as many as 116 noncombatants were killed. Now, these numbers do not include airstrikes in Iraq, Afghanistan or Syria, what the administration calls areas of active hostilities. A new executive order has also been issued, with the aim of decreasing the number of civilian deaths.

United States President Barack Obama's administration said Friday that up to 116 civilians have been killed by U.S. drone strikes in Pakistan, Yemen and other countries where America is not at war. Obama's goal for the release of the numbers is reportedly to create greater transparency about the actions of the U.S. military and CIA in counterterrorism measures against militants plotting attacks against the United States. The announcement covered strikes from the day Obama took office in January 2009 through Dec. 31, 2015. The report by National Intelligence Director James Clapper said the U.S. conducted 473 counterterror strikes, including those by unmanned drones, in this period. Even though the report does not mention the countries where the attacks were carried out, the Associated Press (AP) reported that the Defense Department and CIA have pursued targets in Pakistan, Yemen, Somalia and Libya.

WASHINGTON – The United States on Friday lifted the lid on one of the most controversial tactics of President Barack Obama's secretive counterterrorism campaign, detailing for the first time the number killed in airstrikes in countries like Pakistan and Libya. The White House also released an executive order outlining the steps that should be taken to reduce civilian casualties in America's battle against violent extremism. In a much-anticipated report, National Intelligence Director James Clapper provided fatality estimates for the 473 strikes between 2009 and 2015 that were conducted outside America's principal war zones in Iraq, Syria and Afghanistan. He said between 64 and 116 civilians were killed, and up to 2,581 combatants. Such attacks are typically conducted via drones, though manned warplanes and missiles have also been used.

After escalating one of the most lethal covert operations in U.S. history, President Obama finally made a public estimate of the civilian cost of the nation's secret drone program, which has targeted Islamic militants in remote corners of the globe. Human rights groups immediately challenged the estimate and the amount of transparency from the administration, saying both were too limited. The White House said that 64 to 116 civilians had been wrongly killed in 473 strikes launched by the U.S. government from the time Obama was inaugurated and the end of last year. The vast majority of the attacks were launched by drones, officials said, but the estimate also covers some strikes using manned aircraft. Monitoring organizations estimate the number of civilians killed in U.S. strikes ranges from 200 to more than 1,000.

The Obama administration announced on Friday that the United States has killed a much lower number of civilians in drone strikes in Pakistan, Yemen, Libya, and Somalia than have been previously estimated by outside researchers. A report from the Office of the Director of National Intelligence said that airstrikes (overwhelmingly by drones) killed between 64 and 116 civilians in those four countries from 2009 to 2015. The numbers excluded "areas of active hostilities" such as Afghanistan, Iraq, and Syria. The report is the first time the Obama administration has provided official estimates of the death toll in the secretive drone war. President Barack Obama also issued an executive order on Friday that requires the government to deliver an unclassified report on drone strikes each year that includes the number of combatants and non-combatants killed.

The White House has said that up to 116 civilians have been killed by drone and other US strikes in Pakistan, Yemen, Somalia and Libya since Barack Obama took office in 2009, a figure that has been slammed by watchdog groups as an undercount, which suggests that the real figure could be as high as 1,100. Published by the Director of National Intelligence on Friday, the report said that between January 20, 2009, and December 31, 2015, the US carried out 473 strikes, which killed up to 2,581 "combatants" and anywhere from 64 to 116 civilians. The civilian casualties disclosed in the report were from nations not recognised as "battlefields," and did not reflect US air attacks in "areas of active hostilities" such as Afghanistan, Iraq or Syria. Watchdog and rights groups have long claimed that the US administration does not know how many civilians it has killed and does not do enough to prevent civilian casualties when carrying out counterterrorism operations. Reprieve, an international human rights organisation, said the US government's previous statements about the drone programme have proven to be false by its own internal documents. It said the Obama administration has "shifted the goalposts on what counts as a'civilian' to such an extent that any estimate may be far removed from reality".

The White House said Friday that as many as 116 civilians have been killed by drone and other U.S. strikes in Pakistan, Yemen and Africa since President Barack Obama took office in 2009. In its first public assessment, the administration said the death toll was between 64 and 116 civilians between January 2009 and December 2015, which is significantly lower than civilian casualty estimates by various human rights groups. The number of combatants killed in those 473 strikes was between 2,372 and 2,581. Seeking to create a precedent for his successor, Obama signed an executive order that details U.S. policies to limit civilian casualties and makes protecting civilians a central element in U.S. military operations planning. The order requires an annual release of casualty estimates.
