MANILA, Philippines (AP) — Police clashed briefly in the Philippine capital with about 300 protesters opposed to a planned visit by President Barack Obama and continued U.S. military presence in the country.

Riot police on Tuesday holding up shields across a road to the U.S. Embassy were pushed back by the demonstrators, prompting the police to retaliate with truncheons. No arrests were made and there were no serious injuries in the scuffle.

Carrying placards saying “US troops out now” and “Obama not welcome,” the protesters were allied with the May One Movement workers’ federation. About 500 American soldiers are based in the south where they provide Philippine troops anti-terrorism training. Protesters say their presence violates Philippine sovereignty.

Obama is scheduled to visit the Philippines in April as part of his four-nation Asian tour.
