The Pakistani government has strongly condemned the latest US assassination drone strike in Miran Shah in North Waziristan, which killed 17 people and injured six others.
The US assassination drones on Wednesday fired four missiles at a house in Miran Shah, the main town in the country's troubled northwestern tribal region.
Meanwhile, Pakistani medics reported that the missiles have contaminated the environment with unknown chemicals.
They said the chemicals cause skin, eye and respiratory diseases.
This is the second drone strike on Pakistan after Nawaz Sharif was elected prime minister on June 5, 2013.
Premier Sharif recently blasted the US assassination drone strikes in his country, describing them as a violation of international law and the UN charter.
Islamabad has repeatedly condemned the attacks, saying they violate Pakistan's sovereignty.
Washington claims that the airstrikes target militants, but reports on the ground show that civilians have been the main victims of the attacks.
US President Barack Obama recently defended the use of the controversial drones as self-defense.
The aerial attacks, initiated by former US president George W. Bush, have been escalated under President Obama.
The United Nations and several human rights organizations have already identified the US as the world's number one user of "targeted killings" largely due to its drone attacks in Pakistan and Afghanistan.
