lines 220-228:

"Parts of India, Sri Lanka, and Indonesia were war zones before
the tsunami, and these situations complicated relief efforts.
In Indonesia, for instance, no foreigners had been allowed
into Aceh Province for years because of the fighting. After
so many died, however, foreign help was welcomed. Later,
peace talks were held to aid the relief efforts because workers
were afraid to go into war zones. Groups felt it was time for
Muslims, Hindus, Christians, and Buddhists to work together
as members of a world community."
