US drone strikes have killed 17 civilians in Yemen in just two weeks, according to local rights group, Amnesty International (AI).
According to the group, a US drone struck in the al-Zawiya area on Saturday.
The group said that at least two civilians were killed and four injured in the strike, which took place in the same area as the US-led coalition bombing the group in the north.
The US-backed coalition has been waging a bombing campaign in the region, which is under the control of Iran-backed Houthi rebels.
The UN says more than 6,500 civilians have been killed and another 9,000 injured in air strikes, including more than 2,000 in the last three months.
The UN says that coalition attacks are indiscriminate and violate international law.
The coalition has carried out several airstrikes in Yemen since late March, killing dozens of civilians, including children and women, as part of its campaign to restore Yemen to the status quo ante of the Arab-led peace process.
The strikes have been condemned by many countries as a violation of international law and the UN has imposed sanctions on the coalition.
