Four people were killed in Bangladesh on Monday when clashes broke out between supporters of ruling Awami League and one of its allies on the outskirts of the capital, taking the death toll to 25 in poll-related violence.

Four people, including a man and his son, were killed and 15 others injured in a clash between activists of the ruling Awami League and its ally Jatiya Party (JP) in Dohar sub district, reports said.

Two of the injured were sent to Dhaka in a critical condition.

The JP candidate Salma Islam, who was recently inducted in the cabinet as a junior minister, defeated Abdul Mannan Khan who was the state minister for works.

The two contested the polls on Sunday, though in most places the two parties managed to reach a consensus in fielding common candidates.

The main opposition Bangladesh Nationalist Party (BNP)-led 18 party alliance boycotted the polls and spearheaded a violent campaign to thwart the elections along with its key-ally fundamentalist Jamaat-e-Islami.

Twenty-one people were killed in poll-related violence on Sunday.
