Emir of Qatar Sheikh Tamim bin Hamad Al Thani accused Israel of violating the 11-day-old ceasefire on Tuesday after a series of deadly strikes on Hamas positions.
"We reiterate our condemnation of all Israeli violations and practices in Palestine, particularly the transformation of the Gaza Strip an area unfit for human life (and) the continued violation of the ceasefire," said Sheikh Tamim in an annual address to the Shura Council legislative body.
He also condemned Israeli settlement expansion in the West Bank.
Qatar is a key mediator for the ongoing Gaza truce and Sheikh Tamim said Qatar will continue in that role.
On Sunday, Israel’s military said militants had fired at troops in areas of Rafah in southern Gaza that are Israeli-controlled according to agreed-upon ceasefire lines.
Retaliatory strikes by Israel killed 45 Palestinians, according to the territory's Health Ministry, which says a total of 80 people have been killed since the ceasefire took effect.
