KABUL, Afghanistan (AP) -- An Afghan police official said three explosions went off early Wednesday in the eastern part of the capital, and were followed by sporadic shooting. There were no immediate details of casualties.
The blasts took place hours after President Barack Obama ended a quick visit to Afghanistan, where he marked the first anniversary of Osama bin Laden's death. He spoke to troops and met with Afghan President Hamid Karzai.
Kabul police official Mohammed Zahir said the blasts were heard near a "camp for foreigners" in the east of Kabul.
Ministry of Interior spokesman Sidiq Sidiqi said one of the blasts was a car bomb, possibly driven by a suicide attacker.
Taliban spokesman Zabiullah Mujahid claimed responsibility for the attack.
