Pakistani officials: 4 soldiers killed in 2 attacks in north

Pakistani security officials say suspected militants have launched two separate gun attacks on security convoys in the country's northwest, killing four soldiers and wounding 10 others

PESHAWAR, Pakistan -- Pakistani security officials say suspected militants have launched two separate gun attacks on security convoys in the country's northwest, killing four soldiers and wounding 10 others.

There was no claim of responsibility, but the twin attacks came days after a cross-border attack by dozens of militants killed three soldiers in North Waziristan.

Pakistan and Afghanistan share a rugged 2,400 kilometer (1,500 mile) border. The two nations routinely accuse each other of not taking enough steps to curb the flow of militants within the border region.
