Poland fleshed out details on Monday of "East Shield," a 10 billion zloty ($2.55 billion) program to beef up defenses along its eastern border with Belarus and Russia, saying it hoped to complete the plans by 2028.
The border has been a flashpoint since migrants started flocking there in 2021, after Belarus, a close Russian ally, opened travel agencies in the Middle East offering a new unofficial route into Europe - a move the European Union said was designed to create a crisis.
