Palestinian militant group Islamic Jihad on Wednesday described as "lies" the Israel army's accusations that it was responsible for a strike on a Gaza hospital that left hundreds dead.

"The Zionist enemy is trying hard to evade its responsibility for the brutal massacre he committed by bombing the Baptist Arab National Hospital in Gaza through his usual fabrication of lies, and through pointing the finger of blame at the Islamic Jihad movement in Palestine," it said in a statement.

"We therefore affirm that the accusations put forward by the enemy are false and baseless," it added.
