The judge had been investigating the Dec. 5 clashes between members of Mr. Morsi’s Muslim Brotherhood group and anti-Morsi protesters – one of Egypt’s tensest moments in recent weeks. At least 10 died in clashes that day.

Mr. Morsi alleged that some of those detained during the clashes confessed that they were paid to attack his supporters, a charge the investigating judge refuted.

PAKISTAN

Polio vaccine workers get police protection

LAHORE — Under police guard, thousands of health workers pressed on with a polio immunization program Thursday after nine were killed elsewhere in Pakistan by suspected militants who oppose the vaccination campaign.

Immunizations were halted in some parts of Pakistan, and the United Nations suspended its field participation everywhere until better security was arranged for its workers.

The violence risks reversing recent progress fighting polio in Pakistan, one of three countries in the world where the disease is endemic.

The Taliban have denied responsibility for the shootings. Militants have accused health workers of acting as spies for the U.S. and claim the vaccine is intended to make Muslim children sterile.

CZECH REPUBLIC

Government’s future unclear as party says it quits

PRAGUE — The Czech Republic’s three-party coalition government appears to be heading toward collapse after a junior partner said it would quit.

The Liberal Democrats announced the move Thursday shortly after Prime Minister Petr Necas fired Karolina Peake from the post of defense minister, just eight days after she had been appointed.

Mr. Necas said the major reason for him to dismiss Ms. Peake was “clearly a loss of confidence.”

Ms. Peake leads the centrist Liberal Democrats, the smallest member of the three-party coalition government. She said the party’s leadership called on its ministers to resign from their government posts Jan. 10.
