A Sudanese migrant worker stabbed six people in Israel's Tel Aviv on Sunday, including three Israeli citizens and three foreign workers, police sources confirmed to Xinhua.

The injured, including a 67 year-old man with moderate-serious wounds, have been sent to hospitals.

The police believes that the background to the incident is a fight between two Sudanese migrants. Eyewitnesses tried to break off the fight between the two and were stabbed as well.

Police forces have apprehended the suspect and took him into custody.

There are approximately 50,000 African migrants, mainly from Eritrea and South Sudan, residing in Israel -- mostly concentrated in poor and impoverished parts of Israeli cities, including the poor neighborhood of south Tel Aviv.

The friction between the communities, backed by high crime rates, have caused mounting tensions between the communities and some residents of those communities have called for the ouster of the migrants from their neighborhoods in the recent year.
