[Q]: Oliver Ivanovic  a prominent Kosovo Serb politician  was killed in a brazen drive-by shooting on Tuesday that could reignite ethnic tensions in the region.
An EU-backed Kosovo court sentenced  Ivanovic  in 2015 to a nine-year jail term after it found him guilty of encouraging the killings of captured ethnic Albanian civilians in Kosovska Mitrovica in April 1999.
In February last year  a Pristina appeals court quashed the sentence and ordered a retrial for  Ivanovic   who had been in detention since his arrest in January 2014 until the acquittal.
"Serbs are more afraid of Serbs than Albanians "  Ivanovic  -- a rare Kosovo Serb in that  he  spoke Albanian -- said at the time. "Serb people are afraid to raise their voice" against Belgrade's policy.
A former Serbian state secretary for Kosovo   Ivanovic  was a key interlocutor with NATO  the United Nations and later the EU after the war and was seen as backing dialogue with Kosovo's ethnic Albanians.

[Q]: LONDON (Reuters) - Manchester City âs Argentine striker Sergio Aguero  has broken a rib in a road accident in the Netherlands and will miss Saturdayâs Premier League game at Chelsea with World Cup qualifiers also doubtful.
Manager Pep Guardiola  speaking to reporters before  Aguero  had seen club doctors  said the player was definitely out of Saturdayâs game between league leaders City and champions Chelsea.
He also cast doubt on  Aguero  travelling to Argentina for World Cup qualifiers next month.
âExactly how many days he will be off  I donât know right now â he said  adding that he had âno problemâ with  Aguero  being in Amsterdam.

 Aguero  had earlier posted a picture of  himself  on  his  Instagram account seated in the back of a car thanking Colombian singer Maluma  who was also in the photo  for the invitation.
City are level on 16 points with Manchester United at the top of the table with Chelsea in third place on 13  and  Aguero  is one goal away from equalling Eric Brooksâ all-time club record of 177 goals in all competitions.
The international break follows the weekendâs Premier League matches with  Aguero  in Argentinaâs squad for their last two World Cup qualifiers against Peru and Ecuador on Oct. 5 and 10.

[Q]: The famed New York gossip columnist  Liz Smith  has died at 94.  Her  decades long column in the New York Daily News gave people a look into the lives of the rich and famous and powerful.
For decades  if you wanted to know where a famous person was last night and with whom  you'd see what  Liz Smith  was writing.  Smith  was a famed gossip columnist who chronicled the lives of the rich and powerful in New York's tabloids.  She  died Sunday at the age of 94. NPR's Andrew Limbong has this appreciation.
ANDREW LIMBONG  BYLINE:  Liz Smith  liked to compare gossip to Greek tragedy.  She  was especially fond of this quote from an academic calling gossip an emotional release valve that allows us to express a whole range of human findings - envy  anger  compassion - and to find solace in other people's woes. But  she  herself wasn't that high-minded about it.
 LIZ SMITH : It wasn't just about people doing terrible things all the time. A lot of it was just wannabe news.
LIMBONG: This is  Smith  on NPR in 2009.  She  talked about bringing readers to places where all the rich and famous people hung out.
 SMITH : You wanted to go. You wanted to know how - what would it be? How much did you tip the hat check girl in a place like that? You know  looking through the keyhole at how your betters lived  I guess.
LIMBONG:  Liz Smith  was born in Fort Worth  Texas  in 1923.  Her  babysitter used to take  her  to movies where  she 'd be captivated by movie stars.  She  moved to New York and began ghost writing gossip. In the '70s   she  eventually got  her  own column in the New York Daily News simply titled  Liz Smith .  She  never wanted  her  columns to be mean  and they were far removed from the sort of bloggy online snark of the gossip that came after  her . But  she  had insider information on the likes of Rock Hudson  Elizabeth Taylor  Elaine Stritch.
DOREE SHAFRIR: And you could tell that  she  was writing them sort of from a place of almost  like  love of the people  she  was writing about. Like   she  really enjoyed the world that  she  was writing about and the characters in it.
LIMBONG: That's Doree Shafrir.  She  covers tech for BuzzFeed now  but  she  used to work at Gawker and profiled  Smith  for the New York Observer in 2008.
SHAFRIR: Like a lot of people in media  but probably especially for gossip columnists of  her  era  the line between friends and sources and subjects necessarily got very blurred.
LIMBONG:  Smith  was criticized for not being objective  but  she  didn't pretend to be.  She  told NPR in 2009 about  her  biggest scoop.  She  got it from  her  friend Ivana Trump.
 SMITH : One day Ivana called me and asked me to come to the Plaza Hotel. And when I got there   she  threw  herself  in my arms and told me that Donald didn't want  her  anymore  and that  she  had just gone through all of this plastic surgery to enhance  her  looks. And I tried to give  her  some motherly advice.
LIMBONG: The Trumps' divorce was a big deal  and  Smith  knew what the fallout would look like.
 SMITH : I said  get yourself a PR person who's respectable and defend yourself against him.
LIMBONG: Donald Trump  who was a celebrity real estate developer at the time  wasn't  thrilled Smith  was writing about  his  divorce.
 SMITH :  He  said  he  was going to buy the New York Daily News in order to fire me.
