What are Hezbollah’s military capabilities?
Hezbollah is the Arab world’s most significant paramilitary force with a robust internal structure as well as a sizable arsenal. Backed by Iran, its fighters have gained experience during Syria’s 13-year conflict in which they helped tip the balance of power in favour of government forces.
Hezbollah’s leader, Hassan Nasrallah, had boasted that the group has 100,000 fighters, though other estimates put its troop strength at less than half that. Israel wants Hezbollah to withdraw its elite Radwan Force from the border so tens of thousands Israelis displaced from northern towns and villages can return home.
Hezbollah holds a vast arsenal of mostly small, portable and unguided surface-to-surface artillery rockets, according to the Center for Strategic and International Studies, a Washington think tank. The US and Israel estimate Hezbollah and other militant groups in Lebanon have some 150,000 missiles and rockets. Hezbollah also has been working on precision-guided missiles.
Hezbollah has previously launched drones into Israel and in 2006, hit an Israeli warship with a surface-to-sea missile. Its forces also have assault rifles, heavy machine guns, rocket-propelled grenades, roadside bombs and other weaponry.
During the current conflict, Hezbollah has frequently used Russian-made portable anti-tank Kornet missiles. More rarely, it has launched Burkan rockets that, according to Nasrallah, can carry a warhead that weighs between 300 and 500kg.
In recent weeks, Hezbollah has introduced new weapons including a surface-to-surface missile with a range of 10km and a warhead weighing 50kg.
What are Israel’s military capabilities?
Israel’s military has long been supported by the United States, with US$3.3 billion in annual funding, plus $500 million toward missile defence technology.
Israel is one of the best-armed nations in the wider Middle East. Its air force includes the advanced American F-35 fighter jet, missile defence batteries including the American-made Patriot, the Iron Dome rocket-defence system and a pair of missile-defence systems developed with the US, the Arrow and David’s Sling.
Israel has armoured personnel carriers and tanks, and a fleet of drones and other technology available to support any street-to-street battles.
Israel has some 170,000 troops typically on active duty and has called up some 360,000 reservists for the war — three-fourths of its estimated capacity, according to the International Institute for Strategic Studies, a British think tank. With the war now in its fifth month, many of those reservists have returned home.
Israel has also long maintained an undeclared nuclear weapons programme.
How serious is the latest escalation?
While most analysts believe there is little appetite for a full-blown war by either Hezbollah or Israel, there are fears that a miscalculation by either side could trigger a major escalation. The US, France and other countries have dispatched diplomats in recent weeks to try to tamp down tensions on the border.
Speaking on Tuesday, Nasrallah responded to threats by Israeli officials to launch an offensive if his group does not pull its forces back from the border. “If you expand (the conflict), we will expand,” he said.
Wednesday’s exchange of strikes, some of which hit relatively far from the border area, is a clear indication of the risks that the violence could spill out of control.
The two sides fought a 34-day war in 2006 that ended in a stalemate.
