A woman in Chiang Rai has asked authorities to help find her husband who was abducted in Israel during an attack by the Palestinian militant group Hamas on Oct 7.

Her appeal follows a video showing the kidnapping.

Suntree Saelee, 28, a Hmong villager from Ban Kio Kan in tambon Rim Khong of Chiang Khong district, said she lost contact with her husband, 26-year-old Kong Saelao, during the attack.

Ms Suntree said her husband's co-worker told her that Hamas militants on Oct 7 raided a worker's camp in an avocado orchard in Khirbet Mador, about 3 kilometres from the Gaza Strip, a Palestinian territory.

She said her husband's co-worker managed to escape, but Mr Kong and three other Thais remained in the camp. Later, the co-worker showed pictures and a video clip of Mr Kong in a headlock, being dragged away by a group of men in military uniform, she said.

The pictures showed he was struggling to breathe, she noted.

"When I saw the picture and the clip, I knew it was him," Ms Suntree said in tears. "I am concerned for his safety. Please help him."

She said Mr Kong worked at the avocado farm for 11 months, earning about 50,000 baht per month. She said he was planning to save money to build a new home and buy a car for his family.

He is the only breadwinner in the family, she said, adding he spoke to her every day via an online platform.

She said that on the morning of Oct 7, he told her that a fight had broken out and he heard gunfire and explosions.

The call ended and she lost contact with him about 11.30am, she said.
