Medical officials confirmed the causality figures for all attacks. All officials spoke on condition of anonymity as they were not authorised to release the information.
The attacks come as Iraqi security forces and allied Sunni tribal militias in Anbar have been battling al-Qaida-linked militants from the Islamic State in Iraq and the Levant.
Militants and tribal fighters also control part of the provincial capital, Ramadi. Sporadic clashes there and in surrounding areas continue to take place.
Thousands of families have left the area, fearing a government offencive. Clashes between militants and security forces have killed least 60 people since the violence erupted after the Dec. 28 arrest of a Sunni lawmaker sought on terrorism charges and the dismantling of an anti-government Sunni protest camp in Ramadi.
Today, some government offices in Ramadi opened under tight security and civil servants returned to work, councilman Faleh al-Issawi said. Al-Issawi added that gunmen are still in control of some parts of Ramadi.
