Baghdad, Iraq (CNN) -- A series of roadside bombings in Baghdad killed at least four people and wounded 21 others Tuesday, police said.
Three bombs went off in quick succession at about 3 p.m. in the predominantly Shiite Baghdad neighborhood of Bayaa, killing two people. A few minutes later, two more people died when a couple of bombs exploded near an Iraqi police patrol in the same area of southwestern Baghdad.
Bomb squads defused another two roadside bombs, officials said.
