KABUL, Afghanistan (CNN) - Afghan and international troops killed two insurgents who fired at them while leaving a mosque in southeastern Afghanistan, NATO-led forces said Saturday.
It happened Friday night in Zabul province as troops went to a compound south of Musa Zay where they suspected insurgent activity, the International Security Assistance Force said in a statement.
"As the security force searched the compound, they came under fire from a nearby compound that was later discovered to be a mosque," ISAF said. "The Taliban militants, who were leaving the mosque, fired automatic weapons against coalition troops. The combined force returned fire and killed two insurgents as they advanced towards the patrol."
The force captured a suspected militant in a nearby building and searched the mosque, where they found weapons, multiple blasting caps and materials to make improvised explosive devices, or roadside bombs, ISAF said.
A joint security force in the northern province of Kunduz detained several insurgents for questioning during a search of a compound Friday night, ISAF said. The search team had been acting on information about "insurgent activity" in a car traveling to the compound, and they later found three anti-personnel mines, including one in the militant's car, ISAF said.
More weapons were found Friday in southern Helmand province after Afghan National Police directed an ISAF patrol to a cache containing five mortar rounds and 18 kilograms (40 pounds) of homemade explosives, ISAF said.
The cache, in the Nahr-e Saraj district, was destroyed, ISAF said.
Another cache was found in the Now Zad district of Helmand on Friday containing 46 kilograms (100 pounds) of ammonium nitrate and 4.5 kilograms (10 pounds) of homemade explosives, ISAF said. A joint Afghan and international patrol found the cache in an open field and destroyed it, they said.
Ammonium nitrate-based homemade explosives are used to make roadside bombs, which ISAF says cause the majority of civilian and ISAF casualties in Afghanistan.
