Relations between Azerbaijan and Iran have grown increasingly strained in recent months, with the dispute coming to a head when Baku last week opened an embassy in Israel.

Azerbaijan has also suggested that Iran may have been connected to an attempted assassination of an anti-Tehran Azerbaijani lawmaker a week ago.

In a statement on Thursday, Azerbaijan's foreign ministry said it had summoned Iran's ambassador and expressed "strong dissatisfaction (with) the recent provocative actions demonstrated by his country in relation to Azerbaijan."

The ministry said it was declaring four Iranian diplomats persona non grata and had given them 48 hours to leave the country.
