 Several tigers have trapped five Indonesian men up a tree in a national park on Sumatra island, after mauling a sixth person to death, police say. A 30-member team entered the 7,927 square-kilometer national park on Saturday after villagers’ attempts to rescue the men were thwarted by the site of four Sumatran tigers near the base of the tree, Aceh Tamiang Police chief Adj. "It might need two or three days to walk on foot to the depths of the jungle," he said 
 
 Failed rescue attempt 
 
 Villagers had tried to rescue the men on Thursday but retreated when they saw at least four large Sumatran tigers circling around the base of the tree. “If the tigers are still under the tree, we will have to shoot and anesthetize them so that we can rescue the five [men].” 
 
 The men, all residents of Simpang Kiri village in Aceh Tamiang district, entered the dense national forest in search of the agarwood — known locally as gaharu — a rare and extremely expensive type of heartwood used in the production of aromatic oils and incense. “People keep entering the jungle to look for alim wood because it’s very expensive; up to Rp 5 million ($505) per kilogram. But, well, that’s the risk; there are many tigers and elephants in Gunung Leuser’s jungle.” 
 
 The men were attacked by tigers on Thursday after they caught and killed a tiger cub in a snare meant to catch a deer, police said. Nearby tigers drawn to the scene of the injured cub and pounced on the men, killing and eating 28-year-old David as the five others climbed a tree to safety.
– Five Indonesian men have been trapped up a tree since Thursday, when they accidentally killed a tiger cub and were subsequently chased up the tree by Sumatran tigers. A sixth member of the group was killed by the tigers, the BBC reports. The group was in a national park looking for agarwood, a rare wood used to make incense, which can be sold for around $505 a kilogram. They were trying to trap deer for food, but one of the traps caught a tiger cub instead; adult tigers came to investigate and attacked the men. Those who escaped up the tree used cellphones to call for help. Local villagers tried to rescue them, but were scared off by the four large tigers still circling the tree. Thirty members of a search and rescue team arrived at the Gunung Leuser jungle Saturday, but the police chief says it could take as long as three days for the team to reach the men. "If the tigers remain under the tree, we may have to shoot or sedate them," he adds. (The Jakarta Globe indicates he's talking about shooting them with an anesthetic.) Another group had to be rescued from a similar situation recently.
