At least five people have been killed  in an airstrike carried out by a U.S. drone in Yemen’s southern province of Abyan.
According to Yemeni tribal sources, the attack was carried out on Sunday in the town of al-Mahfad.
The deadly airstrike comes a day after nearly 20 people lost their lives in a similar attack  in the province of Baida.
Saturday’s drone strike targeted a vehicle travelling towards the southern province of Shabwa.
Over the past years, the United States has regularly used unmanned aerial vehicles for attacks and spying in several Muslim countries, including Afghanistan, Pakistan , Somalia and Yemen.
Washington claims the attacks target militants, but evidence on the ground shows civilians usually bear the brunt of such attacks.
The drone strikes have escalated significantly over the past year. This has resulted in a hike in anti-U.S. sentiments in the targeted countries, with people holding numerous protests against the deadly air attacks.
The United Nations says the drone strikes pose a growing challenge  to the rule of international law.
The world body and several human rights organizations have already identified the U.S. as the world's number one user of "targeted killings," largely due to its drone attacks in Pakistan and Afghanistan.
On December 15, 2013, the Yemeni parliament strongly condemned the U.S. drone strikes inside the country. The legislature also passed a law banning the attacks.
