Pakistan ? Suspected militants fired rockets and assault rifles at a security post and a military base in separate attacks in northwestern Pakistan on Wednesday, killing four soldiers, officials said.

In the first attack, militants shot at a security post in Bannu, a troubled town near the North Waziristan tribal region that borders Afghanistan, said Mohammed Noor, a local police official.

Noor said an unspecified number of attackers were killed or wounded when security forces returned fire. Three soldiers were killed in the shootout.

Separately, a soldier was killed and seven others wounded when militants attacked a military base in South Waziristan, another tribal region bordering Afghanistan.
