Two civilians were killed and three others injured in a roadside bomb blast in Kote Sangi area in district five of Kabul City early Tuesday, Kabul police said in a statement.

According to the statement, the incident took place in Kote Sangi at about 7:45 a.m. local time after a roadside bomb exploded, killing two civilians and injuring three others.

The police are currently investigating the case.

Municipality workers called on the government to prevent attacks that take the lives of innocent people.

"The people are very poor and most of them do not have five AFS to buy breakfast and when they come to work they are killed," municipality employee, Mohammad, said.

No group including the Taliban has claimed responsibility for the blast yet.

The blast comes a day after, when one civilian was killed and three others, including two foreign residents, were injured in a suicide attack at Green Village-- a residential compound for NATO contractors-- in Kabul City early Monday.

The incident took place in Qabilby area of Kabul at about 7 a.m. when a suicide bomber detonated his explosive near two vehicles at Green Village, according to security officials.

From the start of the new government, the insurgents in the past weeks have increased their attacks in several parts of Kabul City.
