In Bahrain, authorities have banned public gatherings and increased security in the country after the unrest that killed five anti-government protesters. More than 200 people were injured in the incidents. Bahrain's streets are empty after the clampdown.Justifying the action Bahrain’s Foreign Minister Khalid Al Khalifa said that it was necessary because the demonstrators were polarizing the country and pushing it to the brink of the sectarian abyss.Speaking to reporters after an emergency meeting with his Gulf counterparts in Manama to discuss the unrest, he called the violence regrettable, and said the deaths would be investigated.US Secretary of State Hillary Rodham Clinton has expressed Washington's deep concern and urged restraint. Similar criticism came from Britain and the European Union, and Human Rights Watch urging Bahraini authorities to order security forces to stop attacks on peaceful protesters.Meanwhile as the wave of political unrest continued in the wake of uprisings that toppled leaders in Egypt and Tunisia, one person was killed and 6 others injured in Yemen when police opened fire yesterday on a crowd of protesters in the southern port city of Aden. Another 25 people were wounded in violent clashes between pro- and anti-regime demonstrators in the capital city of Sanaa.
