WANA, Pakistan, Aug 13 (Reuters) - At least nine militants were killed in a missile strike on their training camp in Pakistan's South Waziristan region, near the Afghan border, security officials and residents said on Wednesday.

In a separate incident, a suspected suicide bomb attack outside a police station in the city of Lahore killed three people, police said.

Militant violence has been plaguing the nuclear-armed U.S. ally and helping to undermine investor confidence, as a crisis looms over attempts by a new coalition government to oust unpopular President Pervez Musharraf.

The rupee weakened to a new low of around 75.05/15 to the dollar as investors fretted over political worries. Stocks hovered near two-year lows.

The missile strike in South Waziristan took place on Tuesday night in Bhagar, about 35 km (22 miles) west of Wana, the region's main town.

U.S. forces stationed in Afghanistan have carried out several drone-launched missile attacks this year in Pakistan's border regions, known al Qaeda and Taliban sanctuaries. Dozens of suspected militants have been killed.

An intelligence official in South Waziristan, who declined to be identified, told Reuters that at least four missiles were fired from across the border, hitting one of two militant training camps.
