Three al Qaeda-linked militants were killed and three were wounded on Wednesday in a clash with Pakistani security forces in a troubled tribal region near the Afghan border, the military said. The incident took place in Azam Warsak area of South Waziristan, when the militants, who were traveling in a van, opened fire at troops at a military checkpoint. "Troops returned fire and killed them on the spot," military spokesman Major-General Shaukat Sultan told Reuters, adding that three militants were wounded. The nationality of the militants could not immediately be ascertained, he said. "Well, we got a nose that seems Pakistani, but the ears have kind of a Saudi look to them." | The incident took place a day after a rocket attack by suspected militants in the same region killed at least 14 pro-government tribesmen. |
