Hezbollah hurled dozens of projectiles into Israel early on Wednesday, including a missile aimed at Tel Aviv that was the militant group’s deepest strike yet, and the Israeli military said it would activate reserve troops in response to the rising tensions.

The Israeli military said it intercepted the surface-to-surface missile, which marked a further escalation after Israeli strikes on Lebanon killed hundreds of people.

The missile set off air-raid sirens in Tel Aviv and across central Israel. There were no reports of casualties or damage. The military said it struck the site in southern Lebanon where the missile was launched.

The launch ratcheted up hostilities as the region appeared to be teetering towards another all-out war, even as Israel continues to battle Hamas in the Gaza Strip.

A wave of Israeli strikes on Monday and Tuesday killed at least 560 people in Lebanon and forced thousands to seek refuge.

Fleeing families have flocked to Beirut and the coastal city of Sidon, sleeping in schools turned into shelters, as well as in cars, parks and along the beach. Some sought to leave the country, causing a traffic jam at the border with Syria.

The UNsaid more than 90,000 people have been displaced by five days of Israeli strikes on Lebanon. The UN Office for the Coordination of Humanitarian Affairs said on Wednesday that a total of 200,00 people have been displaced in Lebanon since Hezbollah began firing rockets into northern Israel nearly a year ago, drawing Israeli retaliation.

Hezbollah said it fired a Qader 1 ballistic missile targeting the headquarters of Israel’s Mossad intelligence agency, which it blames for a recent string of targeted killings of its top commanders and for an attack last week in which explosives hidden in pagers and walkie-talkies killed dozens of people and wounded thousands, including many Hezbollah members.

The Israeli military said it was the first time a projectile fired from Lebanon had reached central Israel. Hezbollah claimed to have targeted an intelligence base near Tel Aviv last month in an aerial attack, but there was no confirmation. The Palestinian Hamas militant group in Gaza repeatedly targeted Tel Aviv in the opening months of the war.

The announcement about reserve troops indicated that Israel is planning even tougher action against Hezbollah. The army said it would call up two reserve brigades for missions in the north.

“This will enable the continuation of combat against the Hezbollah terrorist organisation,” the military said.
