Strong aftershocks rocked Papua New Guinea's remote and rugged highlands on Monday, a week after the largest quake to hit the region in almost a century killed at least 31 people.

"We haven't slept. It's been shaking all through the night," said William Bando, provincial administrator of Hela Province, by telephone from Tari, about 40 km from where the shocks hit.
