When people talk about the victims of the Iranian regime, they usually mention Israel, Lebanon, Iraq, Yemen, or Syria. Sri Lanka is almost never part of that conversation. It should be.

While the world focuses on the Middle East, Sri Lanka has quietly become one of the countries most exposed to the darker side of Iran’s global network: drug trafficking, extremist influence, political manipulation, and strategic pressure in the Indian Ocean. Most Sri Lankans still do not fully realise how deep this problem has become.

The Drug Network No One Wants to Talk About

For years, Iran and Hezbollah-linked criminal networks have been connected to international narcotics trafficking operations used to generate enormous amounts of money. Sri Lanka is increasingly caught in the middle of those routes.

The island is no longer just a destination for heroin and crystal methamphetamine (“ice”). It is slowly becoming a transit point and re-export hub. Large quantities of drugs are moving through Sri Lankan waters before being redistributed elsewhere.

The Sri Lankan Navy has done impressive work under extremely difficult circumstances. With support from partners like the United States, authorities have intercepted major shipments over the past few years. But the scale of the problem is alarming.

In 2019, Sri Lankan authorities arrested nine Iranian nationals carrying over 100 kilograms of heroin off the coast of Akurala. Since then, seizures have only grown larger. Between 2025 and 2026, naval operations intercepted huge quantities of heroin and methamphetamine worth billions of rupees.

One operation alone uncovered more than 600 kilograms of narcotics hidden aboard fishing vessels operating in deep southern waters. Authorities later linked the operation to transfers conducted at sea from Iranian-linked ships. These are not isolated incidents.

The Damage Inside Sri Lanka

The social consequences are devastating. Methamphetamine addiction has exploded across the country. A drug that many Sri Lankans had barely heard of a decade ago is now destroying families, villages, and entire communities.

According to Sri Lanka’s National Dangerous Drugs Control Board, methamphetamine-related arrests rose from almost zero in 2017 to around 13,000 within just a few years. Today almost every police station in the country deals with meth-related cases. The damage is visible everywhere:

broken households

rising crime

young people losing their futures

collapsing productivity

and growing pressure on healthcare and rehabilitation systems.

Research studies and local reporting increasingly point to the same reality: villages that once experienced very little serious drug-related crime are now struggling with addiction and local trafficking networks.

The crisis affects all communities. Sinhala rural areas, Tamil communities in the north, and poorer urban neighbourhoods are all suffering. And while ordinary Sri Lankans pay the price, the profits flow into transnational criminal and extremist networks.

The Extremism Problem

Sri Lanka already knows what Islamist extremism can do.

The Easter Sunday attacks in 2019 killed 269 innocent people and shocked the country to its core. One of the most disturbing aspects of the attacks was that several of the perpetrators came from wealthy and educated backgrounds. These were not isolated, desperate individuals acting alone. Some had studied abroad. Some came from privileged families. They were people connected to broader ideological networks.

Years before the attacks, warnings had already been raised about extremist preaching, foreign ideological influence, and radicalisation inside certain circles. Those warnings were often ignored or politicised. That does not mean the wider Muslim community should be blamed. The majority of Sri Lankan Muslims reject extremism completely. But pretending the problem never existed would be equally dangerous.

The Easter attacks proved that even relatively small extremist networks can cause catastrophic destruction when global ideological and financial connections are allowed to grow unchecked. Sri Lanka has not been dealing with this challenge alone.

The United States has become one of Sri Lanka’s most important security partners in combating maritime trafficking and strengthening naval capabilities. American support - including surveillance systems, interdiction support, naval cooperation, and the recent transfer of TH-57 helicopters - has significantly strengthened Sri Lanka’s ability to monitor its waters and intercept trafficking operations. Without that assistance, the challenge facing Sri Lanka would be far more difficult.

The Iranian Naval Question

Iran’s activities near Sri Lanka are not limited to narcotics. The appearance of Iranian naval vessels close to Sri Lankan waters in recent years has raised legitimate strategic concerns.

Sri Lanka sits in one of the most important maritime corridors in the world. Its location in the Indian Ocean makes it geopolitically valuable far beyond its size. It also lies relatively close to Diego Garcia, one of the United States’ most important military facilities in the region. That is exactly why outside powers pay attention to Sri Lanka.

The movements of vessels such as the IRIS Dena and IRIS Bushehr near Sri Lankan waters naturally raised questions in Colombo about sovereignty, regional security, and whether Sri Lanka risks becoming entangled in conflicts much larger than itself. Small countries cannot afford to be naïve about these realities.

The Uma Oya Lesson

Iran’s influence in Sri Lanka has not only come through security concerns. It has also come wrapped in the language of “development” and “friendship.”

The Uma Oya project is one example many Sri Lankans now look back on with frustration. What was presented as a major Iranian-backed development partnership ultimately left Sri Lanka carrying most of the financial burden after sanctions disrupted Tehran’s funding commitments.

Many Sri Lankans believe Iran likely knew sanctions pressure was coming long before the project was completed. Yet Tehran still entered agreements and later continued presenting Uma Oya as a symbol of Iranian generosity.

Meanwhile, Iranian contractors still benefited, and the project became surrounded by controversy over environmental damage, displacement, and corruption concerns. To many Sri Lankans, Uma Oya no longer looks like generosity. It looks like exploitation disguised as partnership.

Sri Lanka Must Learn From Others

Iran did not become influential in countries like Lebanon overnight. It happened gradually through weak governance, economic vulnerability, ideological influence, political fragmentation, and dependency networks that slowly became entrenched.

Sri Lanka today faces several of those same vulnerabilities, including economic hardship, inconsistent foreign policy, political fragmentation, and weak institutional resilience.

Sri Lanka is not Lebanon. But some of the warning signs are uncomfortably familiar. That is why this conversation matters. Sri Lanka cannot afford to ignore narco-trafficking networks, extremist financing, foreign influence operations, and strategic manipulation simply because they develop quietly. By the time the full scale becomes visible, the damage is often already done.
