- Maccabi Tel Aviv lose 5-1 in trip to face Turkish club Besiktas in Europa League
- Match played against a back-drop of rising tensions between Turkey and Israel
- It passes with few problems, though protesters demonstrate outside ground
- European football's secondary tournament begins group stage after qualifying rounds
Some big-name clubs were in action in European football's second-tier competition on Thursday, but most attention was focused on Istanbul for the visit of little-fancied Maccabi Tel-Aviv.
In a match played against a backdrop of escalating tensions between Turkey and Israel, the home team Besiktas triumphed 5-1 in the opening round of the Europa League tournament.
With Turkey having announced the expulsion of Israel's ambassador last week and the suspension of military agreements following a naval incident in May, there were fears the match might not go ahead.
But despite some anti-Israel protests outside Inonu Stadium, the match passed relatively peacefully after Besiktas took the lead in the third minute through Portuguese striker Hugo Almeida, who doubled the advantage before half an hour had been played.
Maccabi, 18-time Israeli champions but third in the league last season, pulled a goal back through Roi Kehat's header four minutes after halftime but could not manage a first victory in the club's fifth meeting with Turkish opposition.
Besiktas -- fifth in last season's Turkish Super Lig and winners of the domestic cup before club officials were arrested in a match-fixing investigation -- hit back immediately through Mehmet Aurelio and Egemen Korkmaz, while Brazilian substitute Edu added the fifth goal two minutes from time.
In the other Group E tie, Dinamo Kiev had to come from behind to draw 1-1 with English side Stoke City.
Ognjen Vukojevic's late goal canceled out Cameron Jerome's 55th-minute opener in Ukraine to deny the visitors victory in the club's first European outing in 37 years.
Last season's losing finalists Braga beat English debutants Birmingham 3-1 away in Group H, while Belgium's Bruges won 2-0 at home to Slovenia's Maribor.
Atletico Madrid, who won the 2009-10 title, cruised to a 2-0 win at home to Scottish side Celtic -- playing after Swiss club Sion lost an appeal after fielding ineligible players.
Striker Falcao scored a record 17 goals in the competition last season as Porto won the title, and he opened the scoring with an early header for his new Spanish club. Brazilian midfielder Diego sealed victory in the second half.
