Three Palestinian fishermen killed 'when Israeli drone exploded in nets'

• Hamas says drone probably in water since 22 February attack
• Palestinian militants have also test-fired rockets into sea

Three Palestinian fishermen who died in an offshore blast had encountered an explosive-laden Israeli drone that had fallen into the sea and blew up in their nets, the Hamas-run interior ministry in Gaza said on Thursday.

An Israeli military spokeswoman had no immediate comment. At the time of the blast on Sunday, the Israeli military had denied it had any involvement in the incident.
