Cluster munitions from the US arrive in Ukraine

The bombs, which open in air to deploy scores of deadly bomblets, are banned in 120 countries, but not in the US, Ukraine or Russia

Cluster munitions provided by the United States have now arrived in Ukraine, the Pentagon confirmed on Thursday.

The munitions - bombs that open in the air and release scores of smaller bomblets - are seen by the US as a way to get Kyiv critically needed ammunition to help bolster its offensive and push through Russian frontlines. US leaders debated the thorny issue for months, before President Joe Biden made the final decision last week.
