At least 14 people were killed and 20 others were injured after a suicide bomber blew himself up at a refugee camp in Iraq's Anbar Province on Sunday.

The attack took place at an aid camp 35 kilometers west of Ramadi. Four children were among the 14 killed.

All the refugees in the camp have been relocated to another camp which is "safer and receives more aid," Al Jazeera reported citing the head of the local council Adnan Fayhan.

There was no immediate claim of responsibility.

Conflict in Iraq had caused the deaths of 411 civilians and injured another 294 people in June, according to a UN report released on Sunday.
