Bahrain has deported an American teacher, saying that tweets and posts she made on websites incited "hatred" against the government and the royal family.
In a statement, the Ministry of Communications said the unnamed teacher was deported for her "activities linked to radical opposition groups," as well as violating the terms of her work permit by working as an unaccredited journalist.

The ministry said she published a number of articles for online journals, including one linked to Hezbollah.

"We cannot have someone teaching impressionable young children who supports an internationally recognized terrorist organization like Hezbollah," said the principal at the school where the woman taught, according to the Bahrain News Agency.

The teacher's expulsion comes as Bahraini opposition groups gear up for a mass protest set for Wednesday.

Tensions in the kingdom remain high after a 2011 uprising in which the majority Shiite population protested against the ruling Sunni minority.

The protests were spurred by uprisings in Tunisia and Egypt.

But the demonstrations failed to gain the traction of other Arab Spring uprisings after a crackdown by authorities in the island state, backed by troops from nearby Saudi Arabia and the United Arab Emirates under the banner of the Gulf Cooperation Council.
