One couple died after a blast in a residential building Wednesday morning in Changsha, capital of central China's Hunan Province, police said.

An initial investigation showed that the blast happened at 7:50 a.m. in a rented flat on the fourth floor of the building in Yuhua District, the district police said. The flat was rented by the couple, Long Wenxian and Liu Yinwu, who had been struggling to divorce, they added.

The blast caused no other casualties. The police excluded the possibility of a gas leak triggered explosion.

The first floor of the building is a wholesale vegetable market. Business resumed Wednesday afternoon.
