WASHINGTON, July 14 (Reuters) - U.S. lawmakersintroduced a bipartisan bill on Tuesday to increase penalties for foreign government agents who threaten people on U.S. soil, a move aimed at countering the rise of what officials call "transnational repression" by countries such as China and Iran.

The bill, put forward by Democratic Senator Adam Schiff and Republican Senator John Curtis, comes after China's ethnic unity law went into effect on July 1, establishing what Beijing says is its right to target certain critics beyond its borders.

July 14 (Reuters) - The U.S. military said on Tuesday it was launching more strikes against Iran.

The strikes began Tuesday afternoon Eastern Time, the U.S. Central Command said in a social media post.

The strikes come as the U.S. is preparing to reinstate a blockade of Iranian shipping after Tehran said it had closed the Strait of Hormuz.

The U.S. blockade is set to go into effect at 1600 E.T. (2000GMT), according to the Central Command.
