Kuwait's Interior Ministry said on Sunday that two border guards were killed "while performing duties," according to a post on X.
The national oil company also announced a "precautionary" cut to its crude production, as the country's military said Sunday it had responded to several drone and missile attacks.
Fuel tanks at Kuwait's international airport were targeted in a drone attack, the military added.
The official Kuwait News Agency said a fire at the airport was brought under control, reporting no "significant injuries.”
The military called the drone attack "a direct targeting of vital infrastructure.”
A separate statement said "some civilian facilities sustained material damage as a result of falling fragments and debris from interception operations.”
