Following the brutal attack on Karachi's international airport, the U.S. government sent drones to strike at various Taliban positions.

After a lull of almost six months, the CIA launched drone strikes against Taliban positions in the area in the border between Afghanistan and Pakistan. According to Reuters, a drone fired a missile at a Taliban hideout killing six on Thursday. The attack was a response to the attack on Karachi's airport.

The airport attack claimed the lives of 38, including 10 militants and has made the Pakistani government switch its opinion on drone strikes slightly. Before the attack, Pakistan protested against what they considered the America's invasion of their sovereignty. However, according to Reuters, Pakistan collaborated with the U.S. in this latest attack.

"The attacks were launched with the express approval of the Pakistan government and army," said a top government official, requesting not to be named, as he was not authorized to discuss the issue with the media. "It is now policy that the Americans will not use drones without permission from the security establishment here. There will be complete coordination and Pakistan will be in the loop. We understand that drones will be an important part of our fight against the Taliban now."

The attack happened some three miles north of Miranshah, the capital of North Waziristan, on Wednesday. The men killed included four Uzbek militants. There was a second attack a couple of hours later.

According to CNN, the second strike targeted other Taliban fighters in the area who were preparing for a strike across the border into Afghanistan. Ten were killed in this attack, including a high-level commander of the Haqqani terrorist group, Haji Gul. Around five drones were flying in the area when the attack happened, report intelligence officers interviewed by CNN. But, despite their support of the first strike, Pakistan publicly protested this attack.

"These strikes are a violation of Pakistan's sovereignty and territorial integrity," the Foreign Office said in a statement. Additionally, these strikes "have a negative impact on the Government's efforts to bring peace and stability in Pakistan and the region."
