(Reuters) - A video posted online shows Los Angeles police scuffling with and shooting a homeless man during a confrontation, The Los Angeles Times reported on its web site. The video, posted on Facebook, shows several uniformed Los Angeles Police Department officers scuffling with a man in a downtown area where homeless people pitch tents at night known as skid row. A series of civilian deaths at the hands of police in the past year has become a touchstone for trouble race relations in the United States, most notably in Ferguson, Missouri, when an unarmed teen-ager was shot and killed by a police officer, triggering weeks of protests and some rioting. The homeless man in the video was declared dead at a hospital shortly after the shooting, the Times reported, citing police spokesman Sgt. Barry Montgomery.

By Brendan O'Brien MADISON, Wis. (Reuters) - A Wisconsin legislative panel was due on Monday to review a state Senate-passed bill that would allow private-sector employees to avoid joining a union or paying union dues even when working under union-negotiated contracts. The measure, which would make Wisconsin the 25th state to enact such a "right-to-work" law, has been cast by supporters as an incentive for keeping and attracting businesses and jobs, while unions brand it as a thinly disguised assault on organized labor. The legislation was narrowly approved on Wednesday by the Wisconsin Senate, which like the state Assembly is led by a Republican majority. Governor Scott Walker, a potential Republican presidential candidate, also supports the legislation.

By Richard Cowan and David Lawder WASHINGTON (Reuters) - Congress narrowly averted a partial shutdown of the U.S. domestic security agency late on Friday night, but the forces behind the chaotic episode remain - fractious Republicans and House Speaker John Boehner's lack of control over them. In five to seven months, the federal debt ceiling will again be reached, and by October Congress must pass spending bills to keep the government running in the new fiscal year. Failing to deal effectively with these issues could have much more damaging repercussions - such as a broad government shutdown or a debt default - than a partial shutdown of the Department of Homeland Security (DHS). Some conservatives speak of ousting Boehner, but it is unlikely they can muster enough votes, while others made clear on Friday that they were willing to take big risks to score ideological points.     Brinkmanship like this, reminiscent of 2013's 16-day federal government shutdown, was supposed to be over.

By Mary Wisniewski and Tracy Rucinski CHICAGO (Reuters) - Winning more support from Chicago’s black community, which makes up about one third of the electorate, will be essential if Jesus “Chuy” Garcia is to cause one of the biggest political upsets of recent years by defeating incumbent Rahm Emanuel in a run-off and become Chicago’s first Hispanic mayor. He will need to overcome tensions between the black and Hispanic communities in the city, aggravated under the 22-year term of Mayor Richard M. Daley, which ended in 2011. There was a widespread perception in the black community that Hispanic supporters of Daley were favored in getting city jobs. A persistently high crime rate, the decision to close 50 schools in mostly poor areas, and a sense that Emanuel is out of touch with the community and its problems has hurt him among black voters, some political activists say.

US Secretary of State John Kerry on Monday warned Israel's prime minister against revealing details at his upcoming speech to US Congress of an Iran nuclear deal that world powers are in the process of negotiating. While he did not mention Benjamin Netanyahu by name, Kerry told reporters in Geneva he was "concerned by reports" that "selective details" of the deal aimed at curbing Tehran's nuclear programme would be revealed in the coming days. Kerry is due to meet his Iranian counterpart Mohammad Javad Zarif in the Swiss lakeside town of Montreux later Monday for talks on the Iran agreement. "The best way to deal with the question surrounding this nuclear programme is to find a comprehensive deal, but not a deal which comes at any costs," he told reporters.

By Matt Spetalnick and Dan Williams WASHINGTON (Reuters) - The United States and Israel showed signs of seeking to defuse tensions on Sunday ahead of a speech in Washington by Israeli Prime Minister Benjamin Netanyahu when he will warn against a possible nuclear deal with Iran. Policy differences over the negotiations with Iran remained firm, however, as Netanyahu arrived in the United States on Sunday afternoon for a speech to Congress, which has imperiled ties between the two allies.
