Fifteen oil workers, including Pakistanis, were killed on Sunday in a head-on collision between two buses in southern Kuwait, officials said.
Seven of those killed were Indian nationals, five were Egyptians and the other three from Pakistan, said Mohammed al-Basri of the state-owned Kuwait Oil Company (KOC).
Two Indian citizens -- one in critical condition -- and a Kuwaiti were also injured in the accident, Basri told AFP.
Fire department spokesperson Colonel Khalil al-Amir said the victims were employees of Burgan Drilling, a private subcontractor for KOC.
Like the other Arab states of the oil-rich Gulf, Kuwait has drawn international condemnation for its track record on migrant workers´ rights and labour conditions.
