what is a global day of jihad

A global day of jihad is a call to arms for Muslims worldwide to participate in a holy war, or jihad, in support of a particular cause. Recently, Hamas issued a global call to arms in support of the "Jihad" in Gaza, urging action on Friday, Oct. 13. The former leader of Hamas has also issued calls for Muslims across the world to participate in jihad this Friday. Islamic Jihad, the second-most powerful Palestinian militant group operating in the Gaza Strip with backing from Iran, is also involved in the recent attacks on Israel.
