Canada on Saturday warned citizens to avoid all travel to Israel, saying the regional armed conflict endangered security.

“The security situation can deteriorate further without warning,” the Canadian government said in a travel advisory issued to raise the risk level for travel to Israel.

“If the armed conflict intensifies, it could impact your ability to depart by commercial means. It may result in travel disruptions, including airspace closures and flight cancellations and diversions,” the travel advisory said.
