Two terror attacks killed at least 67 people in Iraq on Saturday. A car bomb exploding near a bus station in Karbala, one of the Shi'ites' holiest sites, killed at least 56 people. Shortly afterwards a main bridge over the Tigris river in Baghdad collapsed in a blast, killing 11 people. Iraqi officials expressed fears that insurgents were escalating their struggle by targeting the country's most important sites.
