Have any of your national leaders ever died in office due to a wild animal attack?

I already know that:

• King Alexander of Greece died in 1920 due to a monkey bite (specifically a Barbary macaque)
• King Christian V of Denmark died in 1699 after being kicked by a red deer (though TBF he was hunting it)
• (Co-)King Philip of France died in 1132 after his horse tripped over a black pig (a cross-species team effort)
• The legendary King Ragnar Lothbrok of Denmark and Sweden supposedly died in 865 after being thrown in an English snake pit

Are there others? Any presidents or prime ministers?
