At least 32 people were killed on Tuesday in an Islamic State group attack near a refugee camp on the Syrian side of the border with Iraq, a monitor said. 
"At least five suicide attackers blew themselves up outside and inside a camp for Iraqi refugees and displaced Syrians in Hasakeh province," Syrian Observatory for Human Rights chief Rami Abdel Rahman said.
Heavy clashes then erupted between the IS fighters and members of the Syrian Democratic Forces, a US-backed alliance of Kurdish and Arab fighters, some of whose combatants were among the dead, Abdel Rahman told AFP.
