BETHLEHEM (Ma'an) -- The Israeli military on Friday denied that Hamas' military wing shot down an Israeli aircraft over the Gaza Strip.

The al-Qassam Brigades said it shot down a warplane over Gaza and that Israel heavily shelled the area to destroy the wreckage.

"It's not true," an Israeli military spokesman told Ma'an.

Also Friday, Hamas' armed wing said it fired two homemade projectiles at Jerusalem and a long-range missile at the Israeli cabinet building in the city. Israeli police said a rocket fired from Gaza landed in the Jerusalem area, outside the city, on Friday.

A Ma'an reporter in Bethlehem, which is south of Jerusalem, observed a trail from a rocket above the city shortly before a blast was heard, and air raid sirens rang out across the city. There were no immediate reports of injury or damage.

It was the first Palestinian rocket since 1970 to reach the vicinity of Jerusalem.

The al-Qassam Brigades has fired hundreds of rockets at Israeli military bases and across the border since Israel assassinated the group's military commander Ahmad al-Jaabari on Wednesday.
