Iraq's prime minister has warned that a plague of sectarianism is threatening Arab nations, after the most widespread violence there since US troops left.
Nouri Maliki said sectarian conflict had returned to Iraq "because it began in another place in this region" - an apparent reference to Syria.
The violence has left some 170 people dead across the country since Tuesday.
