PORT-AU-PRINCE, Haiti (AP) — The United Nations peacekeeping mission in Haiti said Monday that it is investigating a second death of a Rwandan police officer in as many weeks, adding that it believes the deaths are related.

The body of Sergeant Jeremiah Aloys Nsengiyumva was found Sunday behind a military camp for Uruguayan troops, while the body of Sergeant Hassan Bisangwa was discovered last Wednesday in the town of Jeremie on Haiti's far western coast, the United Nations' force said in a statement.

The statement said that Aloys Nsengiyumva fatally shot Bisangwa and fled. The two were part of a police unit that was deployed to Haiti in December 2011.

The UN force didn't provide a motive for the shooting.

Live rounds unjustified at Guyana protest, says police chief

GEORGETOWN, Guyana (AP) — Guyana's national police chief says lethal force by riot officers was unjustified during a violent protest that left three people dead and 20 others injured.

Chief Leroy Brummel says Interior Commander Clifton Hicken was ordered to use non-lethal methods to disperse hundreds of opposition supporters who were protesting hikes in electricity rates in a mining town on July 18.

Testifying Monday before a fact-finding commission, Brummel described Hicken as a "short man with a hot temper."

The deadly shootings by riot police under Hicken's command prompted furious demonstrators to block bridge access to the remote mining town for a month.

Brummel says he does not know if National Security Minister Clement Rohee gave the order to shoot live rounds.

The commission has subpoenaed documents including Rohee's phone records.

Security foils robbery at Bahamas resort

NASSAU, Bahamas (AP) — Resort security personnel on Sunday foiled an attempted robbery inside the casino of one of the Caribbean's largest and best-known destinations.

Three bandits tried to rob a cashier's cage in the casino of the Atlantis mega-resort in The Bahamas after inundating it with pepper spray, according to a statement from Kerzner International Bahamas, which manages the resort.

Resort officials said the robbery attempt was not visible to casino patrons. It occurred in an employee-only area behind the kiosks where people collect winnings.

The three Bahamian suspects were quickly caught by resort security and taken into custody by the Royal Bahamas Police Force. Their identities were not immediately disclosed.

As a precaution, 16 resort employees were taken to a local hospital after breathing in pepper spray. They were all expected to be treated and released.

Cuba urged to release American contractor

WASHINGTON, USA (AFP) — Forty-four US senators have urged Cuban President Raul Castro to release an American contractor jailed in Cuba with a 15-year sentence, the lawmakers' offices said yesterday.

"Members of the Senate have travelled to your country, written to you and your dignitaries, and employed other creative means to encourage Mr Gross's release," Republican Senator Jerry Moran wrote.

"Yet these attempts thus far have been futile, and Mr Gross's ongoing detention in your country presents a major obstacle to any further actions to improve our bilateral relations," he said.

Gross was arrested in December 2009 and later tried for distributing laptops and communications equipment to the country's small Jewish community, under a US State Department contract.

In 2011, he was sentenced to 15 years in prison for "acts against the independence or territorial integrity" of the communist-ruled island.

Cuba has said it is open to a deal for his release and is awaiting a response from Washington.

The Havana government has said it might be willing to swap Gross for five Cuban agents imprisoned in the United States since 1998 and serving long prison sentences for espionage. Washington, however, has ruled out any such exchange.
