3. Stock market movers -- Ryanair, Fiat Chrysler, Ferrari: Shares in Ryanair (RYAAY) dropped 6% after the low-cost carrier said that higher fuel costs, rising wages and strikes by pilots and regional air traffic controllers had caused its first quarter profit to drop 20% over the previous year.

Shares in Fiat Chrysler (FCAU) (FCA) were down 3% in Milan after the automaker announced the sudden resignation of Sergio Marchionne on Saturday after the longtime CEO suffered complications from surgery.

Replacing him will be the former boss of the automaker's Ram and Jeep brands, Mike Manley.

The company said in a statement that "unexpected complications arose while Mr. Marchionne was recovering from surgery and that these have worsened significantly in recent hours."

Marchionne, 66, will also leave his roles as chairman and chief executive at Ferrari (RACE), which was spun off from FCA (FCAU) several years ago. The luxury carmaker said Louis Camilleri, a Ferrari board member and chairman of Philip Morris International Inc., will become CEO.

Shares in Ferrari also declined 3%.

4. Watching Iran: US President Donald Trump has warned on Twitter that Iran could "suffer consequences the likes of which few have ever suffered before."

The tweet, which was posted late Sunday night, follows an apparent warning from Iran's President Hassan Rouhani, in which he cautioned that Americans "must understand that war with Iran is the mother of all wars and peace with Iran is the mother of all peace," according to Iranian state media reports.

Despite the dramatic rhetoric, US crude oil futures were little changed at $68.50 per barrel.

The United States is preparing to reimpose harsh sanctions on Iran that threaten its oil exports after the Trump administration pulled out of a nuclear deal with the country.

5. Transatlantic transactions: Shares in French IT services firm Atos (AEXAY) slipped 5% in Paris after the company announced a plan to buy the US-based firm Syntel (SYNT) for $3.4 billion in cash.
