Gaza, Iran, Lebanon: If ceasefires are in place, why do strikes continue?

International law sets rules for ceasefires, but who enforces them when violations continue? Three experts explain.

On Wednesday, Israel and Lebanon announced yet another ceasefire – after they had seemingly already agreed to a truce on April 16.

Iran and the United States have formally had a ceasefire in place since April 8. And Israel and Hamas, the Palestinian group, have had a ceasefire in Gaza since October 10, 2025.

Yet Israel’s attacks on Lebanon continue unchecked, with strikes on the Naqoura and Nabatieh districts of southern Lebanon on Friday, resulting in at least one death. Iran and the US have continued to trade periodic attacks that have picked up in intensity in recent days. The Iranian military has also fired missiles and drones at Gulf nations such as the United Arab Emirates, Kuwait and Bahrain, which it accuses of enabling US attacks on Iran during the ceasefire.

And in Gaza, Israel continues to carry out bombings, including one that killed nine people in a residential building this week, despite a supposed truce aimed at ending its genocidal war on the Palestinian territory.

So what does it mean for a ceasefire to be in place when fighting continues? What does international law say? And why do violations so rarely lead to consequences?

Simply put, it’s a pause in fighting designed to create space for negotiations, explained Mark Kersten, assistant professor of criminal justice and criminology at the University of the Fraser Valley.

“A ceasefire is effectively a cessation of hostilities, but typically not understood to be a permanent one,” he told Al Jazeera.

It is also often fundamentally a political agreement rather than a strongly enforceable legal instrument, said Michael Lynk, an emeritus professor at Western University in Canada.

Unlike peace treaties, which often have guarantors responsible for oversight and enforcement, ceasefires can be breached with few immediate legal consequences, Lynk told Al Jazeera.

This is especially true in Gaza and Lebanon, where the United States has acted as the principal broker and overseer. While some countries have criticised Israeli strikes in Lebanon, Lynk says there has been little pressure on Washington for allowing repeated violations.

“A number of Global North countries have criticised the continuing Israeli attacks on Lebanon despite the ceasefire, but they have not called out the US for allowing Israel to repeatedly breach the ceasefires in Gaza and Lebanon.”

Yes, they are, argues Toby Cadman, a British international human rights lawyer and cofounder of Guernica 37 Chambers.
