At least 50 people have been killed and scores others injured after US drones fired several missiles on what Washington calls insurgents' targets in the troubled north-west Pakistan.
The causalities occurred when three drones fired countless missiles on Tuesday afternoon at the funeral procession in the South Waziristan bordering Afghanistan.
The missiles hit the funeral of people who were killed earlier in the day during a similar strike in the volatile region.
At least eight people were killed and a dozen other injured in the first US strike by an unmanned drone aircraft hit near Makeen village, 60 kilometres (37 miles) northeast of Wana, the main town in South Waziristan.
Large numbers of people have been killed in the US drone attacks inside Pakistan since 2006.
US drones have escalated missile strikes in Pakistan since the middle of last year.
The airstrikes are said to be aimed at Taliban militants, but Pakistani media say only ten out of 60 of them have hit the militant hideouts.
Islamabad has repeatedly condemned the US raids, demanding an end to them.
Hundreds of Pakistani civilians have lost their lives in such attacks, which started under the Bush administration.
