Police in "hot pursuit" of criminals would be allowed to cross EU borders, and shoot and arrest suspects on the run, under new proposals tabled by the European Commission.
To combat a rise in cross-border gangs, officers would be given powers to operate in other member states to crack down on drugs, weapons and migrant smuggling operations that exploit the bloc's open borders.
"We propose a better police cooperation on the ground, that's boots on the ground," Ylva Johansson, European Commissioner responsible for home affairs, said.
The 27-page proposal sets out plans to simplify "hot pursuits", "cross-border surveillance" and "joint police" operations, replacing some 60 outdated crime-fighting agreements.
