Protesters opposing Egyptian President Mohammed Morsi march despite a nighttime curfew in the city of Suez on Jan. 28. Egyptian protesters defied a nighttime curfew in restive towns along the Suez Canal, attacking police stations and ignoring emergency rule imposed by Islamist President Morsi to end days of clashes that have killed at least 52 people. Egypt's army chief said political strife was pushing the state to the brink of collapse - a stark warning from the institution that ran the country until last year as Cairo's first freely elected leader struggles to contain bloody street violence.

Political opponents spurned a call by Mohammed Morsi for talks on Monday to try to end the violence. Instead, huge crowds of protesters took to the streets in Cairo and Alexandria, and in the three Suez Canal cities - Port Said, Ismailia and Suez - where Morsi imposed emergency rule and a curfew on Sunday.

"Down, down with Mohammed Morsi! Down, down with the state of emergency!" crowds shouted in Ismailia. In Cairo, flames lit up the night sky as protesters set vehicles ablaze.

The demonstrators accuse Hosni Mubarak's successor Morsi of betraying the two-year-old revolution. Morsi and his supporters accuse the protesters of seeking to overthrow Egypt's first ever democratically elected leader by undemocratic means. Continue reading the full story.

Nepalese police detain anti-government protesters near the airport in Katmandu, Nepal, Monday.

The Associated Press reports: Nepalese police detained anti-government protesters who were demanding the resignation of Nepalese Prime Minister Baburam Bhattarai near the airport in Kathmandu, Nepal, on Monday. The protesters tried to block Bhattarai's motorcade as he returned home Monday from a U.N. conference in Brazil. Bhattarai has been leading a caretaker government since last month, but opposition parties want him to resign so a new government that includes representatives from all major parties can take over and conduct elections in November.

Anti-government protesters throw back canisters of tear gas shot by the police in Sitra, southeast of Manama, on Thursday, Jan. 26.

Reuters reports —  Bahrain's Interior Ministry said on Thursday that a man detained by police over "acts of sabotage" died in hospital while in custody, without elaborating on the cause of death.

Bahrain last year crushed protests led by its Shi'ite Muslim majority demanding an end to sectarian discrimination and limits to the authority of the Sunni ruling family, relying in part on backing from troops from fellow Sunni-led Gulf monarchies.

More than a thousand people were detained in the crackdown, at least four of whom died in official custody. An inquiry Bahrain commissioned into the protests and government crackdown found systematic abuse of detainees, including torture. Full story.
