KABUL, Afghanistan (AP) — Gunmen stormed a building in the city of Mazar-i-Sharif Sunday evening, prompting a shootout with security forces, an Afghan official said.

Sher Jan Durani, spokesman for the provincial police chief in Balkh province, confirmed that a number of attackers had entered a building near the Indian consulate and begun firing on security forces. He said the gunmen carried RPGs and light weapons, and that security forces had surrounded the area. There were no immediate reports of casualties, he said.

Earlier on Sunday, an Afghan army helicopter crashed in the eastern province of Logar, killing three Afghan soldiers.

Defense Ministry spokesman Dawlat Waziri said the MI-17 crashed Sunday because of technical problems. He said two other soldiers were wounded.

The provincial governor's spokesman Salim Saleh confirmed the incident, saying it took place around 1:30 p.m. local time.

Late last year, Taliban insurgents ambushed a military-contracted helicopter that made an emergency landing in northwestern Afghanistan. The militants killed three people in a shootout and captured 16 others who were on board.
