Police officers and bus attacked in Londonderry

Police officers have come under attack and a bus window has been damaged during disturbances in Londonderry.
It happened in the Galliagh area of the city on Sunday afternoon.
Police said a large group of young people had gathered in the vicinity of Fergleen Park at around 15:45 BST, where some of the youths threw stones at officers.
The window of a bus was damaged a short time later, at around 16:15, at Fairview Road.
'Serious consequences'
Police Service of Northern Ireland (PSNI) Sgt Irvine appealed for anyone with information to come forward.
"Our neighbourhood team will continue to patrol in this and other areas, but we would appeal to parents to know where their children are and what they're doing when not at home," the officer said.
"The young people involved may not always realise the impact of their actions, but these could potentially see them facing serious consequences that could affect their life choices in the future," Sgt Irvine added.
Bus services to the area were suspended for a time on Sunday evening but resumed as normal on Monday morning.
Translink said they could continue to monitor the situation in close liaison with the police and local community representatives.
They appeal for witnesses to attacks on buses to report them to the police, Crimestoppers or Translink.
Earlier this month, a number of bus services were withdrawn in the Ballymagroarty area of Derry after a the windows of a bus were smashed as it travelled along the Glenbank Road.
