Seven Killed After Ship Hits Tower in Italian Port
* Worst maritime disaster in Italy since Costa Concordia
* Seven dead, two missing, four injured and in hospital
* 50 metre-high control tower collapses into water
* Investigation focusing on ship's engine, steering mechanism
(Reuters) - Seven people were killed and two were missing after a container ship crashed into a control tower in the northern Italian port of Genoa, rescuers said on Wednesday.
The tower, which was more than 50 metres (160 feet) high and looked much like the ones common at airports, collapsed into the water late on Tuesday after being struck by the prow of the vessel, the Jolly Nero.
Among the dead were three of its officers, a coastguard statement said. Divers were searching for two missing people at the site and cranes were sifting through debris along the shore.
The other victims have yet to be identified. Two were recovered from the wreckage of the tower's lift, a firefighters' spokesman said.
The accident happened as staff were changing shifts and there were 13 people in the tower when it was struck, the coastguard said.
As well as the dead and missing, officials said four people were injured and had been taken to hospital. Two were seriously hurt and one had lost a foot, investigators said.
"The main injuries are fractures, crushed body parts, significant traumas," emergency services doctor Andrea Furgani said.
The crash occurred shortly after 11 p.m. (2100 GMT) in calm conditions as the Jolly Nero was manoeuvring out of the port.
Genoa prosecutor Michele Di Lecce has opened an investigation and is focusing on a possible malfunction of the ship's engine or steering mechanism, judicial sources said.
In testimony to parliament after visiting the port, Transport Minister Maurizio Lupi also said an engine problem could be behind the incident, which took place in "perfect" weather conditions.
Other causes could have been a human error or problems with tow cables fixed to two tug boats that were accompanying the ship out of the harbour, Lupi said.
The crash is the most serious maritime accident in Italy since the Costa Concordia luxury cruise liner struck a rock and capsized off the island of Giglio in January 2012, killing 32 people.
"There's no logical explanation because two tug boats were moving the ship and there was a port pilot on board and sea conditions were optimal," the head of the Genoa Port Authority, Luigi Merlo, said.
All that was left of the tower was a leaning metal stairway.
The Jolly Nero, which is 238 metres-long (781 foot) with a gross tonnage of 40,594 tonnes, is owned by local operator Ignazio Messina and Co.
"A thing like this has never happened, we are devastated," said Stefano Messina, one of the directors of the family-owned firm, who was in tears when he spoke to a local TV channel.
