This is what passes for normal now in Bahrain, a Sunni-ruled island nation that's home to the headquarters of the US Navy's 5th Fleet and where most people follow the Shiite branch of Islam.
Crackdown on protests
For the past two months, the country's rulers have imposed a harsh crackdown on a protest movement that was among the first to spring up after Egypt's Hosni Mubarak was pushed from that country's presidency in February.
The crackdown has included bulldozing Shiite mosques, arresting mainstream opposition politicians and closing the country's main opposition newspaper.

The protest marches that dominated life for weeks here are gone, as is the iconic Pearl Square monument, which had been the gathering point.
Still, every night in many Bahraini villages and towns, residents gather on their rooftops at 8:15 and again at 10 to issue what's become a protest cry: "Allahu akbar," or "God is great." Police deploy helicopters to try to drown out this protest, and to drop tear gas canisters on the rooftops, residents say.
Detention instead of treatment for wounded protesters
The Sunni government has seized control of the health care system, and that's the police's secret weapon for tracking down protesters, which some experts say violates international conventions that require the humane treatment of all civilians and nondiscriminatory treatment of the injured and sick.
