Verify if the sentiment of the following document towards the entity Harry Hohmeister is Negative . Lufthansa ’ s ( LHAG . DE ) first flight from Berlin to the United States in over 16 years took off on Wednesday   although a slow start to sales shows the difficulties involved in trying to replace the gaps left by insolvent rival Air Berlin . FILE PHOTO : A Lufthansa Airbus A321 - 200 plane is seen at Tegel airport in Berlin   Germany   November 2   2017 . REUTERS / Axel Schmidt Germany ’ s second largest carrier Air Berlin ( AB1 . DE ) filed for insolvency in August and carried out its last flight at the end of last month   leaving a gap in the market for long - haul flights from the German capital in particular . “ Of course bookings are slow at this stage  ”  Lufthansa board member Harry Hohmeister  told Reuters at Berlin ’ s Tegel airport ahead of the departure of the flight to New York ’ s JFK on Wednesday .  He  said that usually Lufthansa would give 12 months notice of a new long - haul route   or eight months at a minimum   but in this case it had only six weeks to sell tickets ahead of the first flight . “ The next four weeks will be difficult   then we get a peak at Christmas time and then it will develop better   otherwise we wouldn ’ t do it  ”  Hohmeister  said . Lufthansa has traditionally shied away from long - haul flights from Berlin   instead flying intercontinental routes from its hubs in Frankfurt and Munich .  Hohmeister  said the Lufthansa group was currently looking at other long - haul options from Berlin   but that any would likely be flown by its budget arm Eurowings . Lufthansa is currently awaiting EU approval for a deal to take over large parts of Air Berlin   which will see it adding 81 planes to the group . The collapse of Air Berlin means Berlin Airports will see a dip in passenger number growth this year after a period of strong demand . Britain ’ s easyJet ( EZJ . L )  which is planning to take over some Air Berlin operations at Tegel   has said it expects to run a reduced schedule this winter from the airport . “ We expect that new partners will quickly bring growth  ” Berlin Airports CEO Engelbert Luetke Dalderup said   urging Lufthansa to “ never say never ” to the idea of Berlin as a hub .

Verify if the sentiment of the following document towards the entity Sarath Fonseka is Positive . Tensions escalated Wednesday over the arrest of Sri Lanka's former army chief  Sarath Fonseka  with violent clashes outside the Supreme Court  where his wife petitioned for his immediate release.
 Opposition parties who backed Fonseka in his failed challenge to President Mahinda Rajapakse in January elections also demanded his release and said they feared for his safety in military custody.
 Fonseka was arrested by troops at his office in Colombo on Monday night and  according to the defence ministry  will be court-martialled on charges of conspiring against the government.
 Anti-riot police used tear gas and water cannon Wednesday to break up a clash between thousands of Fonseka supporters and ruling party activists outside the capital's Superior Courts complex.
 As order was restored  Fonseka's wife arrived to file a petition for her husband's release. Supreme Court officials said a hearing had been fixed for Friday.
 Opposition lawmaker Karu Jayasuriya said the combined opposition was seeking the support of the influential Buddhist clergy in pressuring the government to free Fonseka and curb a crackdown on dissidents and rival politicians.
 "We are speaking to all religious leaders and will have a series of religious events to seek the release of General Fonseka from custody and ensure more democratic freedoms " Jayasuriya said.
 Sri Lanka's former peace facilitator  Norway  joined the United Nations  France and the United States in expressing concern over Fonseka's arrest  saying it risked impeding progress towards "lasting political stability".
 Earlier this month  Rajapakse sacked a dozen senior military officers in an unprecedented purge. The defence ministry said the officers were a threat to national security. Party workers from Fonseka's office were also arrested.
 The Sri Lankan government is also concerned about Fonseka's apparent willingness to testify at any probe into alleged war crimes committed by Sri Lankan troops last year in the final stages of the conflict with Tiger rebels.
 "I am not prepared to protect anyone  if they have committed war crimes " Fonseka said before his arrest.
