BAGHDAD, Iraq (CNN) -- Sunni gunmen stormed two Shiite homes in Diyala province overnight and slaughtered 21 men in front of their families, Diyala authorities said Saturday.
The attacks north of Baghdad add to the series of sectarian reprisals that followed Thursday's assault on the Baghdad Shiite enclave of Sadr City, considered the single worst attack in Iraq since the war began.
At least 200 people were killed and 250 more injured in that attack, which Sunni militants are widely believed to have carried out.
In response, officials have imposed a strict curfew and shut down Baghdad's airport, forcing Iraqi President Jalal Talabani to postpone a trip to Iran on Saturday. He was to meet with Iran's President Mahmoud Ahmadinejad to discuss ways for Iran to help stabilize Iraq.
