At least 130 people were killed and several others injured in an alleged Saudi-led coalition airstrike on a wedding party in Yemen. The wedding party attack occurred on Monday evening in the Red Sea village of Al-Wahijah in the central Yemeni province of Taiz, reported Associated Press.

The Saudi-led coalition, however, denied its involvement in the deadly attack. "The coalition did not conduct any airstrikes in the area over the past three days. This is completely false," coalition spokesman Brigadier General Ahmed al-Assiri said on Tuesday, according to Guardian.

The U.N. human rights office said the attack on the wedding ceremony was one of deadliest attacks on civilians since the beginning of conflict in Yemen. "This may be the single deadliest incident since the start of the conflict," agency's spokesman Rupert Colville said, according to Press TV.

U.N. Chief Ban Ki-moon condemned the airstrikes and called on all parties involved in the Yemeni conflict to immediately halt all military activities. "Any intentional attack against civilians is considered a serious violation of international humanitarian law. Violations of international law should be investigated through prompt, effective, independent and impartial mechanisms to ensure accountability," he said in a statement.

At least 2,355 civilians were killed and 4,862 wounded in the conflict ridden country since March, the U.N. human rights agency said, according to VOA News.
