Hamas and Islamic Jihad on Monday claimed joint responsibility for a bombing in Israel's commercial hub of Tel Aviv that killed the assailant and wounded one person. 

The armed wings of both groups, which have fought Israeli forces in Gaza, said in a statement that they "carried out the suicide operation that took place Sunday evening in the city of Tel Aviv," threatening more such attacks in Israel "as long as the occupation's massacres, the displacement of civilians and the policy of assassinations continue."

Israeli police claimed earlier on Monday that the "powerful" explosion in Tel Aviv late on Sunday was a "terror attack."

The blast came shortly after U.S. Secretary of State Antony Blinken arrived in Tel Aviv to push for a ceasefire in Gaza after more than 10 months of conflict, and as fears grow of a wider, regional conflagration. 

Blinken, on his ninth regional tour since the start of the Israel-Hamas conflict, met with Israeli Prime Minister Benjamin Netanyahu and other top Israeli officials.
