Baghdad (CNN) -- Three bombings targeted Shiite pilgrims Monday in and around Karbala, Iraq, killing at least 33 people, officials said. A suicide car bombing in the small town of Twareej, just outside Karbala, killed at least 20 people and wounded 35 others, Interior Ministry officials said. Earlier, at least 13 people died when a car bomb exploded in a Karbala bus station crowded with Shiite pilgrims, who had traveled to the city for a religious observance, according to the Interior Ministry. Another 45 people were wounded in the attack, which came near the peak of the Arbaeen, a religious observance that is one of the holiest days in the Shiite religious calendar.
