The Tel Aviv Stock Exchange index rose by 0.3% at the opening of today's session, without any major reaction after the Iranian attack on Israel last night. In contrast, the indices of major Gulf markets declined, amid fears of an expansion of the war in the region.

Iran launched a drone and missile attack on Israel, its first direct attack on Tel Aviv, in retaliation, raising fears of an expansion of the war in Gaza.

The Iranian attacks came in response to a suspected Israeli airstrike on the Iranian embassy compound in Damascus on April 1 that killed senior Iranian Revolutionary Guard officers.

Gulf markets fall

In contrast, major Gulf stock markets fell during today's session, after the Iranian attack on Israel. The Saudi stock market fell 1.8% to 12,557 points, the Qatari main index fell 1.3%, the Kuwaiti main index fell 0.79%, and the Muscat Stock Exchange index fell 0.19%.

Most Arab markets are closed today due to Eid Al Fitr holiday.

The development would bring renewed focus to the Strait of Hormuz, a major energy shipping route through which about a fifth of the world's daily oil supplies pass.

For his part, Israeli Prime Minister Benjamin Netanyahu pledged today, in a tweet via the X platform, that Israel will achieve victory.

The Israeli military said it shot down 99 percent of the more than 300 drones and missiles launched by Iran, while Iran said its missiles hit Israeli military targets.

Open airspace

Elsewhere, Israel, Jordan, Iraq and Lebanon reopened their airspace today after it was closed late Saturday as Iran launched drone and missile attacks on Israel.

Jordanian aviation authorities said air transport operations had resumed, while Iraqi aviation authorities said security risks had now been overcome.

An Emirates spokesman said on Sunday that the company had cancelled some flights and rerouted others, following the Iranian attack on Israel, according to Reuters.

Earlier yesterday morning, the Revolutionary Guards seized a ship linked to Israel and took it into Iranian territorial waters. The seized ship is flying a Portuguese flag and is operated by Zodiac, a company owned by an Israeli businessman.
