Hamas has reportedly claimed responsibility for the attack.

'The attack is shocking,' Amnesty International said. 'There is no justification for the targeting of civilians.'

'Deliberately killing civilians violates fundamental principles of international law and we call on Palestinian groups and individuals to cease such attacks immediately,' the organisation said.

'Palestinian and Israeli authorities have a responsibility to bring to justice people within their jurisdiction who ordered and facilitated the bombing,' Amnesty International said. 'In doing so they must act strictly in accordance with international humanitarian and human rights standards.

'This cycle of violence can only be halted by placing human rights at the heart of ceasefire or peace negotiations, and a commitment by all parties to uphold the fundamental human rights of all.'
