Airports across Europe stepped up security after attacks in Belgium, which took the lives of at least 13 people, according to local media.
Key air transport hubs in Paris, London and Frankfurt stepped up security measures after terror attacks in Belgium's Brussels, which targeted the city's airport and subway system.
Despite changes in airport security at London's Heathrow and Gatwick airports, the United Kingdom's Home Office told Sputnik that across-the-board security measures have yet to be introduced. France boosted transport security, while President Francois Hollande is holding an emergency meeting to discuss further measures.
The blasts came several days after Belgian police arrested Salah Abdeslam, the top suspect in the 2015 Paris attacks, which took the lives of 130 people.
