Bahrain's Interior Ministry says a homemade bomb has wounded two policemen in the capital Manama.

The ministry said the two received severe injuries from what it termed an act of "terror" Friday.

The island nation with a native population of more than 550,000 has been gripped by near-nonstop turmoil and increasingly divided along sectarian lines since February 2011, when Shiites inspired by the Arab Spring wave of revolutions began an uprising calling for a greater political voice in the Sunni-ruled country.
