Mississippi passes strictest abortion law

Mississippi's governor has just signed into law the tightest abortion restrictions in the US.

The bill bans most abortions after 15 weeks, with no exceptions for rape or incest.

The only exemptions are in cases where there is a foetal abnormality that is "incompatible with life", or the mother's life is in danger.

Mississippi previously banned abortions from 20 weeks. Critics say the new law is unconstitutional.
