UN Secretary-General Ban Ki-moon on Monday condemned an earlier bomb attack in the village of Daih, Bahrain, which led to the death of three policemen.

"Such acts of violence cannot be justified by any cause," said a statement issued here by Ban's spokesperson on Monday night.

In the statement, the UN chief conveyed his sympathies and condolences to the families of the victims and the government of Bahrain.

"The secretary-general strongly believes that a genuine and all-inclusive political dialogue is the only way forward," the statement said.

Ban also urged all Bahrainis to come together to create a "conducive environment" for promoting reconciliation, the statement added.

Three policemen were killed in a terror blast in Bahrain. The Interior Ministry said the policemen died while dispersing a group of anti-government protestors who gathered illegally in Daih village, police said on Monday.

This is the deadliest attack on security force since 2011 in which three policemen died on a single day in a terror blast.

Scores of anti-government protestors gathered in Daih village following the third day funeral procession of Jaffar Al Durazi. He was in custody on suspicion of weapons smuggling.

Al Durazi died last month at the country's main hospital Salmaniya Medical Complex as he suffered from sickle cell anaemia.
