Authorities in Alexandria, Egypt, have tightened security after a suicide bomber attacked a Christian church on Jan. 1, killing at least 21 people.
“We are stressing now on guarding churches,” Adil Labib, governor of Alexandria, told state-run Nile TV.
The Egyptian health ministry said 79 people were wounded in the attack, the Middle East News Agency reports.
U.S. President Barack Obama has deplored the attack, says CNN.
