Gunbattle said to be occurring near Afghan military academy

An Afghan official and an eyewitness say blasts have been heard and a gunbattle is occurring near a military academy in the capital Kabul.

Afzal Aman, commander of the Army Garrison, says an army unit was attacked with hand grenades around the area of the Marshal Fahim academy Monday.

Hashmat Faqeri, a resident near the site, told The Associated Press he has heard sounds of explosions and he confirmed a gunbattle is ongoing near the academy.

There is no word of any possible casualty. All roads leading to the military academy are blocked by the Afghan security forces.

No one immediately claimed responsibility for the attack, but Taliban insurgents have increased their attacks on high-profile targets in Kabul especially in recent days.
