KUALA LUMPUR, Malaysia -- Malaysian authorities said Sunday that they have discovered a series of graves in at least 17 abandoned camps used by human traffickers on the border with Thailand where Rohingya Muslims fleeing Burma have been held.
The finding follows a similar discovery earlier this month by police in Thailand who unearthed dozens of bodies from shallow graves in abandoned camps on the Thai side of the border. The discoveries are shedding new light on the hidden network of jungle camps run by traffickers, who have for years held countless desperate people captive while extorting ransoms from their families.
Most of those who have fallen victim to the trafficking networks are refugees and impoverished people from Burma and Bangladesh, part of a wave of people who have fled their homelands to reach countries such as Malaysia, where they hope to find work or live free from persecution.
As Southeast Asian governments have launched crackdowns amid intensified international pressure and media scrutiny, traffickers have abandoned camps on land and even boats at sea to avoid arrest.
Malaysian Home Minister Zahid Hamidi said police were trying to identify and verify "mass graves that were found" in the region near the Thai border.
"These graves are believed to be a part of human trafficking activities involving migrants," he said, adding that police have discovered 17 abandoned camps that they suspect were used by traffickers.
There was no immediate word on how many bodies had been recovered. Zahid said each grave probably contained one to four bodies and that authorities were in the process of counting.
He said he expected more camps and graves to be found "because they have been there for quite some time. ... We are still investigating, but I suspect they have been operating for at least five years."
Local media outlets said the graves were found in two locations in the northern state of Perlis. The state borders southern Thailand's Songkhla province, where at least 33 bodies were found earlier this month.
According to the Malay-language Utusan Malaysia newspaper, police found 30 large graves containing hundreds of corpses in mid-May in forests around the Perlis towns of Padang Besar and Wang Kelian.
The English-language The Star said 100 bodies were found in a single grave in Padang Besar. It said police forensics teams had arrived there Friday night to investigate, and the area had been cordoned off.
Human-rights groups and activists say the area on the Thai-Malaysia border has been used for years to smuggle people, including Rohingya Muslims, a persecuted minority group in Burma.
In many cases, they pay smugglers thousands of dollars for passage but are instead held for weeks or months, while traffickers extort more money from families. Rights groups say some have been beaten to death, and The Associated Press has documented other cases in which people have been enslaved on fishing boats.
Since May 10, more than 3,600 people -- about half of them from Bangladesh and half Rohingya from Burma -- have landed ashore in Indonesia, Malaysia and Thailand. Thousands more are believed to be trapped at sea in boats abandoned by their captains.
Last June, the U.S. downgraded Thailand and Malaysia to Tier 3 -- its lowest category -- in an annual assessment of how governments handle human trafficking.
Malaysia and Indonesia announced last week that they would provide temporary shelter for up to one year for people recently found or still stranded at sea. The U.S. has said it will settle some of them permanently.
Four Malaysian navy ships began searching for boats Friday, but their operation is limited to Malaysia's territorial waters. The Pentagon said Thursday that Washington was readying air patrols to aid in the search, but a U.S. Embassy spokesman in Bangkok said the offer of assistance was still awaiting clearance.
The Rohingya, numbering about 1.3 million in Burma, have been called one of the most persecuted minority groups in the world. Long denied basic rights, they have been driven from their homes in mob attacks in Burma's Rakhine state several times since 2012.
More than 140,000 were displaced and are now living under apartheid-like conditions in crowded camps. More than 100,000 more have fled by sea.
Burma is often called Myanmar, a name ruling military authorities adopted in 1989.
