Palestinian Authority security forces are fully prepared for the visit of US President Barack Obama this week, a PA security forces spokesman said. Adnan Dmeiri told Ma\'an that security services have completed security and logistical preparations for Obama\'s visit. Military intelligence services, national security forces, police and the presidential security services have been preparing for the visit for the past few weeks. \"Palestinian security forces preserve the right to have full sovereignty,\" he added. US helicopters flying across the West Bank on Monday were carrying US security and administrative delegations, Dmeiri said. Palestinian security is in contact with US forces about security arrangements, but PA forces are fully in charge during Obama\'s visit to areas in the West Bank, he added.
