How do ballistic missiles work and what's their range?
In response to Israeli attacks on its nuclear sites and senior military figures, Iran has launched hundreds of ballistic missiles towards Israel, with some striking targets on the ground.
Although Israel intercepted many of the incoming missiles, several breached its defences, causing significant damage and casualties, including hits on central Tel Aviv and other areas.
The exact size of Iran's ballistic missile arsenal is unclear, but it is widely considered one of the largest and most advanced in the region.
In the following visual explainer, Al Jazeera unpacks how ballistic missiles work and how they are being used in the ongoing conflict.
Ballistic missiles are long-range weapons designed to deliver conventional or nuclear warheads by following a ballistic, or curved, trajectory.
Launched using powerful rocket engines, these missiles shoot upwards into the upper atmosphere or even space, travelling at incredibly high speeds. Once their engines are cut off, the missile follows a predetermined path, re-entering the Earth's atmosphere in a steep descent before striking its target.Ballistic missiles can travel distances ranging from a few hundred kilometres to more than 10,000 kilometres across continents.
Ballistic missiles are classified based on their ranges:
Ballistic missiles travel at extremely high speeds, allowing them to travel thousands of kilometres in just minutes.
The speed at which they travel is measured in Mach, a unit equivalent to the speed of sound; for example, Mach 5 means five times the speed of sound.
Some, usually shorter-range, ballistic missiles reach supersonic speeds (faster than Mach 1, or about 1,225km/h or 761 miles per hour), while others, usually longer-range missiles, can travel at hypersonic speeds – greater than Mach 5 (6,125km/h or 3,806mph).
The distance between Iran and Israel is about 1,300km to 1,500km (800-930 miles). Ballistic missiles from Iran travelling at Mach 5 can reach Israel in roughly 12 minutes, though the exact time depends on the missile type and the launch site.
What makes ballistic missiles especially dangerous is their combination of long range, high speed, and how difficult they are to intercept.
Their fast, high flight path gives defence systems little time to react, and when they re-enter the atmosphere, they descend even faster, making interception even more difficult. Some missiles also deploy decoys or other countermeasures to trick radar and missile defences, making them harder to intercept.
Iran has also used cruise missiles against Israel. Unlike ballistic missiles, cruise missiles fly low and steady like pilotless planes, which helps them sneak past air defences. Although they travel much slower than ballistic missiles, giving air defences more time to intercept, their low flight path makes them harder to detect. Their ability to manoeuvre allows them to change course, fly around obstacles and evade missile defences.
While ballistic missiles from Iran can reach Israel in about 12 minutes, cruise missiles may take almost two hours, and drones can take up to nine hours.
Iran has developed a range of ballistic and cruise missiles over the past three decades. The graphic below summarises some of Iran's most prominent missiles and their ranges.Israel has an advanced missile arsenal, including long-range and nuclear-capable systems, developed with decades of support from the United States. The graphic below highlights some of Israel's most notable missiles along with their respective ranges.The Israeli air defence relies largely on what is known as the Iron Dome system, which is equipped with a radar that detects an incoming projectile, as well as its speed and direction.
Other systems intercept medium- and long-range missiles. The David's Sling intercepts missiles ranging between 40km (25 miles) and 300km (186 miles). The Arrow System intercepts missiles with a range of up to 2,400km (1,491 miles).

Layoff notices delivered to hundreds of Voice of America employees
Layoff notices have been sent to 639 employees of Voice of America (VOA) and the United States agency that oversees it, effectively shutting down the outlet that has provided news to countries around the world since World War II. The notices sent on Friday included employees at VOA's Persian-language service who were suddenly called off administrative leave last week to broadcast reports to Iran following Israel's attack. Three journalists working for the Persian service on Friday, who left their office for a cigarette break, had their badges confiscated and weren't allowed back in, according to one fired employee. In total, some 1,400 people at VOA and the US Agency for Global Media, or 85 percent of its workforce, have lost their jobs since March, said Kari Lake, Trump's senior adviser to the agency. She said it was part of a 'long overdue effort to dismantle a bloated, unaccountable bureaucracy'. 'For decades, American taxpayers have been forced to bankroll an agency that's been riddled with dysfunction, bias and waste,' Lake said in a news release. 'That ends now.' VOA began by broadcasting stories about US democracy to residents of Nazi Germany, and grew to deliver news around the world in dozens of languages, often in countries without a tradition of free press. But President Donald Trump has fought against the news media on several fronts, with the complaint that much of what they produce is biased against conservatives. That includes a proposal to shut off federal funding to PBS and NPR, which is currently before Congress. 'Death' of independent journalism Most VOA employees have been on administrative leave since March 15, their broadcasts and social media posts mostly silenced. Three VOA employees who are fighting the administration's dismantling of VOA in court were among those receiving layoff notices on Friday. 'It spells the death of 83 years of independent journalism that upholds US ideals of democracy and freedom around the world,' plaintiffs Jessica Jerreat, Kate Neeper and Patsy Widakuswara said in a statement. The Persian-language employee, who spoke on condition of anonymity because of the ongoing legal case, was in the office Friday when colleagues were barred from re-entry. The person was afraid to leave for the same reason – even though authorities said their work had been halted – until receiving a layoff notice. Steve Herman, VOA's chief national correspondent who was in the process of retiring to take a job at the University of Mississippi, called the layoffs an 'historic act of self-sabotage with the US government completing the silencing of its most effective soft-power weapon'. It's not clear what, if anything, will replace VOA's programming worldwide. The Trump-supporting One American News Network has offered to allow its signal to be used. Although plaintiffs in the lawsuit called on Congress to continue supporting VOA, Herman said that he is not optimistic that it will survive, even if a Democratic president and Congress take over. For one thing, every day it is off the air is another day for viewers and readers to get into another habit for obtaining news. 'I believe that the destruction is permanent,' Herman said, 'because we see no indication in the next fiscal year that Congress will rally to fund VOA.' By the time another administration takes power that is more sympathetic to the outlet, 'I fear that VOA will have become forgotten,' he said.
