An armoured Israeli military vehicle drives along Israel's border with Egypt's Sinai peninsula, near the Nitzana crossing in this picture taken January 30, 2014. An Islamist insurgency boiling in the desert peninsula has claimed casualties among the Multinational Force and Observers (MFO), requiring new and often cumbersome precautions. And while participating countries do not say so publicly, there has been some behind-the-scenes debate over the MFO mandate at a period of unprecedentedly close Israeli-Egyptian security cooperation. In northeastern areas of Sinai once strictly demilitarised, Egypt, with Israel's consent, now routinely brings in troops,tanks, fighter jets and helicopters to fight insurgents.

An European Union Monitoring Mission (EUMM) observer uses a pair of binoculars to watch Russian soldiers construct a fence along Georgia's de-facto border with its breakaway region of South Ossetia in the village of Dvani, about 120 km northwest of Tbilisi, October 4, 2013. The fence put up by Russian forces on the boundary between Georgia and South Ossetia has been a source of dispute between Russia and Georgia. The breakaway region recognized by Russia as independent had been the focus of a brief 2008 war between the two countries. REUTERS/David Mdzinarishvili (GEORGIA - Tags: POLITICS) 

A general view of a 6200 tonnes heavy and 123-year-old brick building that was moved 60 m (0.037 miles) west from its original location is seen at its original location at the railway station in Zurich Oerlikon May 22, 2012. With the translocation of the 80 m (252 ft) long building, it paves the way for the Swiss Federal Railways (SBB) to expand its tracks at Switzerland's seventh-largest railway station Zurich Oerlikon. Switzerland's real estate investment company Swiss Prime Site has invested roughly CHF 12 million ($12.6 million) in order to preserve the former executive office building of the tool and machinery factory Oerlikon (MFO).
