ISLAMABAD: Pakistan on Friday warned of accountability in case Israel attacked Global Sumud Flotilla (GSF) that has been en route to Gaza to deliver humanitarian aid, the Pakistani foreign office said on Tuesday.

The flotilla set sail from Tunisia on Sunday, with organizers and participants saying they were determined to break Israel’s siege of Gaza and deliver urgently needed humanitarian aid.

The departure of the convoy, which is carrying activists from more than 40 countries aboard, from the port city of Bizerte was delayed after two flotilla vessels came under attack last week.

Speaking at a weekly press briefing, Pakistani foreign office spokesman Shafqat Ali Khan reiterated that the flotilla has informed about its objectives of delivering aid to Gaza and raising awareness about the needs of Palestinian people.

"We therefore call on everyone to refrain from any unlawful or violent act against the Flotilla, to respect international law and international humanitarian law," Khan told reporters in Islamabad. "We recall that any violation of international law and human rights of the participants in the Flotilla, including attack against vessels in international waters or illegal detention, will lead to accountability."
