MANILA, Philippines?Senator Francis Pangilinan on Thursday called for an investigation into reports US soldiers joining the Balikatan military exercises in the Bicol Region are being given sex workers every night.

?This needs to be investigated and exposed. This is condemnable,? said Pangilinan, who initiated a resolution in the Senate calling for a review of the US-RP Visiting Force Agreement.

During his recent visit in the region, Pangilinan said he was approached by concerned citizens, claiming that at least two batches of eight to 10 women were being sent nightly to US soldiers, ?checking in at 10 p.m. and are out by 4 a.m. the following morning.?

?Every time a pimp brings in 10 women, all will be taken. Then they?ll bring another batch of 10,? Pangilinan, quoting the locals, said.

The service US servicemen were also allegedly seen by the residents in hotels and bars with very young women.

?We worked so hard to get rid of prostitution and cleaning our reputation when the US military bases finally left our shores,? Pangilinan said. ?The Philippines is not a whorehouse for US soldiers.?
